Q:Cast iron into a casting. What is the state of the matter, change, sublimation?: The graphite crucible has good thermal conductivity and high temperature resistance, and the thermal expansion coefficient is small in the process of high temperature use, and has a certain anti strain property for hot and cold quenching. The corrosion resistance of acid and alkaline solution is strong, and it has good chemical stability.

Q:Corundum crucible and graphite crucibleSome enterprises use graphite crucibles in vacuum furnaces, while some larger ones use corundum crucibles. What I want to know is the advantages and disadvantages of corundum crucibles and graphite crucibles: Graphite crucible is a high temperature resistant and difficult to sinter material. But the biggest problem must be used in vacuum or reducing atmosphere. Otherwise, graphite is easily oxidized at high temperature. Moreover, this crucible is more expensive

Q:What can replace a graphite crucible?: Installation of crucible:1. The crucible base (crucible station) requires the same crucible bottom diameter or greater height of the crucible platform to prevent fire from spraying into the crater above the crucible.2. Using refractory bricks, the crucible station shall be a round brick, flat without bending, and shall not be made of brick or semi - uniformly, preferably imported graphite crucibles.3. The unit is placed in a crucible melting, melting of the solution in the center, the coke powder, made of ash or refractory cotton mat, in order to avoid the crucible and crucible Taiwan rod, erected after the crucible, need to melt and the need for the central level (highest level ruler).4. The size of the crucible and furnace fit, the distance between the crucible and the molten wall, shall be suitable for at least 40mm.5. When the furnace crucible is installed, the gap in the gap below the contact brick, the crucible should be set aside about 30-50MM dollars gap, not the bottom pad, things, mouth and smooth cotton, refractory material, furnace wall. Requires a fixed furnace wall, refractory bricks, thermal expansion, space heating after the required corrugated cardboard, 3mm thick pad crucible.

Q:Can a graphite crucible be used with gas burners or torches?: Yes, a graphite crucible can be used with gas burners or torches. Graphite has a high melting point and is resistant to heat, making it suitable for use with these heat sources. Additionally, graphite is chemically inert and does not react with most substances, making it a reliable choice for various applications in laboratory or industrial settings.

Q:What is the recommended fluxing method for a graphite crucible?: To ensure optimal results and prolong the lifespan of the crucible, it is advised to preheat the graphite crucible before usage, as per the recommended fluxing method. This preheating process aids in the elimination of any moisture or impurities that might be present. Subsequently, the flux material can be introduced once the crucible has been adequately preheated. The flux material serves the purpose of preventing oxidation of the graphite crucible and facilitating the removal of impurities from the molten metal. The specific application and the metal being melted will determine the type and quantity of flux material to be employed. It is crucial to adhere to the manufacturer's guidelines regarding the appropriate flux material and application technique in order to achieve optimal outcomes and ensure the crucible's longevity.

Q:Can graphite crucibles be used for thermal analysis?: Thermal analysis does not usually involve the use of graphite crucibles. Graphite crucibles are primarily utilized for high temperature purposes, such as the melting and casting of metals, as well as chemical reactions that necessitate intense heat. When conducting thermal analysis, diverse techniques are employed to examine the physical and chemical properties of materials during temperature changes. Some of these techniques comprise differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and measurements of thermal conductivity, among others. To carry out these types of analyses, specific equipment and materials are required. Generally, ceramic or metal crucibles are utilized due to their superior thermal conductivity and stability at high temperatures, which ensures precise and dependable measurements. These crucibles are engineered to endure thermal cycling and provide a controlled environment for the analyzed sample.

Q:Which is a good quality graphite crucible?: The ordinary graphite crucible can not guarantee the safety in the high temperature environment, moreover, the conduction speed is slow in the test, which is not good for the experiment.

Q:What are the different methods of preheating a graphite crucible?: Preheating a graphite crucible can be done using various methods, depending on specific requirements and available equipment. Here are some commonly used techniques: 1. Induction Heating: An electromagnetic field is generated by an induction coil, rapidly heating the graphite crucible. Known for its efficiency and quick heating capabilities, induction heating is widely employed. 2. Resistance Heating: By passing an electric current through the graphite crucible, heat is generated due to the resistance encountered by the crucible material. Specialized resistance heating elements or wires are needed for this method. 3. Gas Flame Heating: Placing the graphite crucible over a gas burner or torch gradually raises its temperature using the heat from the flame. This method is commonly employed in smaller-scale applications or situations where electricity is not readily accessible. 4. Electric Furnace Heating: Electric furnaces are specifically designed for heating crucibles. The crucible is placed inside the furnace, which generates heat through resistance heating elements. This method offers controlled and uniform heating, making it suitable for precise temperature requirements. 5. Microwave Heating: In specific cases, microwaves can be utilized to preheat graphite crucibles. This method utilizes microwave radiation to generate heat within the crucible. However, it requires specialized equipment capable of withstanding high temperatures and is not as commonly used as other methods. It should be noted that the choice of preheating method depends on factors such as crucible size, desired heating rate, and availability of specific equipment. Proper preheating ensures that the graphite crucible reaches the required temperature before being used for applications such as metal melting, chemical reactions, or thermal analysis.

Q:New energy, crystal, silicon and other research and development, production, because the crucible rotary table heating device, there is no good solution to share?: 1. features:(1) according to the actual shape and size design, including 3 dimensional geometry to meet your equipment.(2) provide heater longer moisture antichemical silicone rubber material.(3) simple paste and touch on your parts, through vulcanization, adhesives, or fasten pieces, etc..

Q:Can graphite crucibles be used for metal powder atomization?: Yes, graphite crucibles can be used for metal powder atomization. Graphite crucibles are often preferred for their high melting point, excellent thermal conductivity, and chemical resistance. These properties make them suitable for the high-temperature process of metal powder atomization, where fine metal powders are produced by rapidly cooling molten metal. Additionally, graphite crucibles provide good control over the atomization process, making them a popular choice in industries such as aerospace, automotive, and additive manufacturing.
