- Q: What graphite crucible is used to smelt aluminium by electromagnetic induction heating?
- Electromagnetic induction heating is the heating of graphite, and can soon rise to 1000 degrees, but aluminum is a magnetic material, will block the electromagnetic field, so this scheme is not feasible
- Q: Is it possible to customize the shape or design of a graphite crucible?
- Yes, it is possible to customize the shape or design of a graphite crucible. Graphite is a highly versatile material that can be molded and shaped into various forms. Graphite crucibles are often used in industries such as metallurgy, foundries, and laboratories for melting and casting metals. To customize the shape or design of a graphite crucible, manufacturers use specialized techniques such as CNC machining or graphite molding. CNC machining involves using computer-controlled machines to precisely shape the graphite material into the desired form. This method allows for highly accurate and complex designs to be created. Alternatively, graphite molding is a process that involves compressing graphite powder into a specific shape using a mold. This method is often used for simpler and more standard crucible shapes. Customization of graphite crucibles can include altering the dimensions, adding handles or spouts, or creating unique designs to suit specific applications. The customization process allows for the crucible to be tailored to the specific requirements of the user, ensuring optimal performance and efficiency. It is worth noting that while customizing the shape or design of a graphite crucible is possible, it may come with additional costs and lead times. This is because the customization process requires specialized equipment and expertise. Therefore, it is essential to communicate with the manufacturer or supplier to discuss the customization options, feasibility, and any associated costs.
- Q: How do you determine the appropriate crucible lid for a graphite crucible?
- In order to determine the appropriate lid for your graphite crucible, there are several factors that should be considered: 1. Consider the size and shape of the crucible. It is important for the lid to fit securely onto the crucible, creating a tight seal. Take measurements of the diameter and height of the crucible and select a lid that matches these dimensions. 2. Ensure that the lid material is compatible with the high temperatures and chemicals used in the crucible. Graphite crucibles are commonly used for applications involving high temperatures, so the lid should be able to withstand extreme heat without warping or cracking. 3. Take into account any ventilation needs that may be required for your specific process. Some processes release gases or vapors during heating, so it may be necessary to choose a lid with a vent or hole to allow for proper ventilation. This will help prevent pressure buildup and potential damage to the crucible. 4. Consider any application-specific requirements that are unique to your process. For example, if you need to observe the contents of the crucible during heating, you may want to select a lid with a transparent window or a removable cover. 5. It is also important to check the recommendations provided by the crucible manufacturer. They may offer specific lid options that are designed to work well with their crucibles. By taking these factors into consideration, you will be able to determine the most suitable crucible lid for your graphite crucible. This will ensure optimal performance and safety during your heating processes.
- Q: Who can give a detailed description of the degree of volatility of graphite at various temperatures?
- General use temperature of 1600-1800 degrees Celsius, 3000 degrees Celsius for softening temperature, generally high temperature volatile is inside the impurities, not graphite itself. I do graphite, has not seen graphite volatilization
- Q: Can graphite crucibles be used for crystal growth?
- Yes, graphite crucibles can be used for crystal growth. Graphite has several properties that make it suitable for this purpose. First, graphite has a high melting point, which allows it to withstand the high temperatures required for crystal growth. Second, graphite has good thermal conductivity, which ensures uniform heat distribution during the growth process. Third, graphite is chemically inert, meaning it does not react with most substances, which is important for maintaining the purity of the crystal being grown. Additionally, graphite crucibles are often used in crystal growth techniques such as the Czochralski method, where a seed crystal is dipped into a molten solution and slowly withdrawn to grow a larger crystal. In summary, graphite crucibles are commonly used and well-suited for crystal growth due to their high melting point, good thermal conductivity, and chemical inertness.
- Q: Why can't a f containing compound be used in a porcelain crucible, a Lilac Garden?
- The main components of a porcelain crucible are alumina and silica, while fluorine is very oxidizing, and at high temperature fluorine will replace the oxygen in the oxide and corrode the crucible. Although the contents of the crucible may not be sufficient to penetrate the crucible, the accuracy of the experiment will be affected by the fact that the crucible is not dissolved in the content of the component.
- Q: How to judge the thermal stability of rubber oil?
- 1.2 sample containers, crucibles, aluminium crucibles, copper crucibles, platinum crucibles, graphite crucibles, etc. shall not react with specimens and reference materials. 1.3 air source, air, nitrogen and so on, the purity should reach the purity of industrial gas. 1.4 the cooling temperature of the cooling device of the cooling device should be up to -50 degrees centigrade. No enthalpy change occurs in the range of test temperature of 1.5 reference substance. Typical reference materials are calcined alumina, glass beads, silicone oil, or empty containers. Store in a dryer.
- Q: Is it possible to achieve controlled pouring with a graphite crucible?
- Controlled pouring using a graphite crucible is indeed achievable. Various industries, such as metal casting and melting, widely utilize graphite crucibles due to their unique properties. These crucibles possess a high melting point, excellent thermal conductivity, and good resistance to thermal shock, making them suitable for handling high-temperature substances. To achieve controlled pouring with a graphite crucible, several factors must be taken into account. Firstly, it is essential to adequately preheat the crucible to the desired pouring temperature. This ensures that the molten material maintains its desired temperature throughout the pouring process, preventing premature solidification. Secondly, the design of the crucible and its pouring lip should enable precise control over the flow of the molten substance. Shaping the pouring lip allows for a steady and controlled stream, reducing the risk of splashing or spilling. Moreover, the operator's expertise and experience play a vital role in achieving controlled pouring. They must possess a comprehensive understanding of the poured material, its characteristics, and the appropriate pouring techniques. Additionally, they should be mindful of potential hazards and take necessary precautions to ensure safety throughout the pouring procedure. In conclusion, achieving controlled pouring with a graphite crucible is feasible by considering proper preheating, suitable crucible design, and skilled operators. These factors contribute to achieving precise and controlled pouring for a variety of applications.
- Q: Can quartz ceramic crucibles instead of graphite crucibles?
- Graphite heat resistance is much higher than that of quartz ceramics; graphite can be more than 2000, while the highest resistant quartz ceramics 1700 degrees.
- Q: How do you see the conch alive?
- Slightly touched conch soft tissue, it will be sensitive to contraction, the more sensitive, the more fresh, but not fresh or dead
