Q: Is the silicon carbide crucible good for use? What's the difference between an ordinary graphite crucible and a graphite crucible?: The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, using advanced refractory raw materials, high-tech formula developed a new generation of high-quality silicon carbide crucible, this product has a large volume density, high temperature resistant, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.

Q: What's the difference between crucible furnace and non crucible furnace in die casting industry?: The crucible furnace, as the name suggests, is a furnace with a crucible. There are cast iron crucibles, cast steel crucibles, some alloy steel crucibles, graphite crucibles, clay crucibles and carborundum crucibles from the crucible material.

Q: How does the porosity of graphite affect the performance of a crucible?: The performance of a crucible is influenced by the porosity of graphite in several ways. Initially, the ability of the crucible to withstand high temperatures is determined by its porosity. If the graphite crucible is more porous, it will exhibit greater resistance to thermal shock, enabling it to endure rapid temperature changes without cracking or breaking. This characteristic is particularly crucial in situations where the crucible is exposed to extreme heat, as it guarantees the crucible's integrity and prevents any compromise to the material being heated. Additionally, the porosity of graphite also impacts the crucible's heat retention abilities. A more porous crucible possesses a larger surface area, facilitating the absorption and retention of heat for extended periods. This feature proves advantageous in applications that require consistent and prolonged heating, as it enables the crucible to provide a stable temperature environment for the processed material. Moreover, the porosity of graphite can influence the crucible's resistance to chemical corrosion. A crucible with higher porosity allows for improved diffusion of chemicals, thereby reducing the likelihood of chemical reactions occurring on the crucible's surface that could degrade its performance. This factor holds particular significance in industries such as metallurgy or chemistry, where corrosive substances are commonly utilized. In conclusion, the porosity of graphite plays a vital role in determining the performance of a crucible. It affects the crucible's resistance to thermal shock, its ability to retain heat, and its resistance to chemical corrosion. Therefore, it is imperative to select a crucible with the appropriate porosity in order to ensure optimal performance and durability in diverse high-temperature applications.

Q: How long can a graphite crucible last?: The lifespan of a graphite crucible can vary depending on several factors such as usage, temperature, and handling. Generally, a well-maintained graphite crucible can last for several months to a few years, with regular inspections and proper care.

Q: How do you prevent oxidation of the graphite crucible during use?: In order to prevent oxidation of the graphite crucible during usage, there are several steps that can be taken: 1. Crucible pre-conditioning is essential: It is crucial to gradually heat the graphite crucible before using it. This process aids in the elimination of any residual binders or impurities on the crucible's surface, thereby reducing its susceptibility to oxidation. 2. Application of a protective coating: The graphite crucible can be safeguarded against oxidation by applying a protective coating. There are various coatings available, such as boron nitride or zirconium oxide, which create a barrier between the crucible and the surrounding atmosphere, thus minimizing the likelihood of oxidation. 3. Atmosphere control is key: The atmosphere in which the crucible is utilized plays a vital role in preventing oxidation. Whenever possible, it is advisable to employ a controlled atmosphere, such as vacuum or inert gas (e.g., argon or nitrogen), during the heating process. This helps to minimize the presence of oxygen, which can result in oxidation. 4. Avoidance of abrupt temperature changes: Rapid temperature fluctuations can cause thermal shock, leading to cracks and increased vulnerability to oxidation. To prevent this, it is important to ensure a gradual and controlled heating and cooling process. 5. Crucible cleaning after usage: After each use, it is imperative to clean the graphite crucible thoroughly in order to eliminate any residues or contaminants that may promote oxidation. Utilize an appropriate cleaning agent and gently scrub the surface to ensure its cleanliness. By adhering to these preventive measures, the oxidation of the graphite crucible during usage can be significantly reduced, thus prolonging its lifespan and maintaining its effectiveness.

Q: What are the considerations for selecting a crucible support for graphite crucibles?: When choosing a support for graphite crucibles, it is important to take several key factors into account. Firstly, the support must be compatible with graphite crucibles. Graphite has unique characteristics, such as a high melting point and thermal conductivity, which necessitate a support that can withstand these conditions without deforming or reacting with the crucible material. Common materials used for this purpose include silicon carbide or clay graphite, as they possess high temperature resistance and are compatible with graphite. Secondly, the size and shape of the crucible support should be considered. The support should securely hold the graphite crucible in place, preventing any movement or tipping during heating or pouring. It should also provide sufficient stability to bear the weight of the crucible and the material being melted or processed. The design and construction of the crucible support are also important factors to consider. It should have a sturdy and robust structure to ensure long-term durability and reliability. Additionally, the support should be easy to handle and maintain, facilitating convenient handling and cleaning. Moreover, the thermal properties of the crucible support are essential. The support should have good thermal conductivity to evenly distribute heat to the crucible, ensuring uniform heating and preventing any hotspots or thermal stress. It should also have low thermal expansion to minimize the risk of cracking or damaging the crucible during heating and cooling cycles. Finally, cost and availability play significant roles in the decision-making process. Crucible supports can vary in cost depending on the material, design, and size. Evaluating the budget and availability of crucible supports is crucial to ensure they meet the requirements and constraints of the specific application. In conclusion, selecting a crucible support for graphite crucibles requires thorough consideration of factors such as compatibility, size and shape, design and construction, thermal properties, and cost. By taking these factors into account, one can choose a suitable crucible support that guarantees optimal performance and longevity for graphite crucibles.

Q: Aluminum crucibles can be used to heating soda?: I don't know much about the reaction, but the melting point of aluminum is lower than that of soda ash.

Q: Can waste circuit boards be recycled?: Silver is also one of precious metals. The recovery of silver from waste liquid is as follows:The waste liquid is adjusted by 20% sodium hydroxide, and the pH value is between 8-9. Then sodium sulfide solution is added to precipitate the silver sulfide;(1): +2Na+: 2Ag+Na2S==Ag2S(2) water washed silver sulfide precipitate to residual sulfide, filtered water, the silver sulfide in the crucible, heating to 800-900 DEG C for desulfurization, remove the cooling.(3) to 100 (weight) silver slag, add borax 10, sodium chloride 5 mix and then burning to crude silver crucible.

Q: What material of graphite is used in arc furnace production?: Today, large diameter semi graphitic carbon electrodes have been adopted in industrial silicon electric furnaces. Can effectively save production costs, and the technology is relatively mature.

Q: Is it possible to achieve a controlled atmosphere inside a graphite crucible?: Achieving a controlled atmosphere inside a graphite crucible is indeed possible. Graphite crucibles find common usage in high-temperature applications, particularly for melting metals and alloys. Various methods can be employed to achieve a controlled atmosphere. One approach involves the use of a gas purging system. This entails introducing a specific gas into the crucible to create the desired atmosphere. For instance, if an inert atmosphere is necessary, gases like argon or nitrogen can be used to displace any oxygen or other reactive gases present. The gas flow rate and pressure can be adjusted to maintain the desired atmosphere. Another method involves creating a sealed environment around the crucible. This can be accomplished by utilizing a furnace or an induction heating system equipped with a gas-tight enclosure. By controlling the gas composition and pressure within this enclosure, a specific atmosphere can be maintained surrounding the crucible. Moreover, the choice of crucible material is crucial to consider. Graphite possesses high thermal conductivity, allowing for rapid heat transfer. However, it can also react with certain gases or metals at elevated temperatures. Hence, selecting the appropriate grade of graphite and ensuring proper crucible conditioning are essential in maintaining a controlled atmosphere. Ultimately, by utilizing suitable equipment and employing effective techniques, it is feasible to establish a controlled atmosphere inside a graphite crucible, thereby enabling precise control of the environment during high-temperature processes.
