Detailed Product Description

high purity graphite block, has good mechanical and chemical behaviours

High Purity Graphite is suitable for the graphite( anode, inner grid, outside grid,reverberation pole, and excitation) which is applied in all kinds of small size silver rectifier, and for the graphite(anode, grid) which is appplied in electronics tubes. It is used in monocrystal furnace as grapite heater, heating preservation cover,crucibles etc. The specification that our company mainly produces is as follows: Dia.40mm---275mm; height 100---150 and 2*120, 200*200, 200*320(Cube); Thickness 50---12. The special request can be customized.

Q: Are there different sizes available for graphite crucibles?: Indeed, graphite crucibles are offered in various sizes to cater to diverse needs and applications. These crucibles come in a plethora of sizes, ranging from petite ones suitable for jewelry making or minor laboratory experiments to more substantial ones used for industrial purposes such as metal casting or melting. The necessary size of the crucible is contingent upon the quantity of material to be melted or processed, as well as the unique demands of the application at hand. Consequently, an array of sizes is made available to satisfy distinct requirements and guarantee the optimal and proficient utilization of graphite crucibles.

Q: Melting the iron in the graphite crucible. Does the graphite in the crucible turn into carbon and it melts into the steel?: Graphite is a very pure substance, and graphite is a transition crystal. The carbon atoms in each layer of graphite are bonded by non-polar covalent bonds, and the molecular layers of graphite are joined by intermolecular forces. The melting point of the graphite crucible is 3652 to 3697 degrees (sublimation), so the graphite crucible is high temperature resistant.

Q: How does the wall thickness of a graphite crucible affect the melting process?: The wall thickness of a graphite crucible affects the melting process by influencing the rate of heat transfer. A thicker wall can retain heat for a longer period, resulting in slower melting times. Conversely, a thinner wall allows for faster heat transfer, leading to quicker melting. Additionally, the thickness can also impact the crucible's durability and resistance to thermal shock.

Q: How is graphite formed?: The company has advanced production and processing equipment, modern production management, perfect product testing means, a good service network and strong development capabilities. For customers to produce all kinds of special-shaped, high-precision graphite products! Such as: graphite plate, graphite rod, graphite block, graphite crucible, graphite anode plate, graphite mold, graphite lining, graphite bearing, Shi Mohuan, graphite tube, graphite pad, graphite electrode and so on.

Q: Electromagnetic induction heating device into the copper coil heater, to use more power consumption to reach the melting temperature of iron?: The roommate's induction heater comes from a copper tube with water through it

Q: How does the gas permeability of graphite affect crucible performance?: The gas permeability of graphite plays a crucial role in determining the performance of a crucible. Graphite is known for its excellent gas permeability, meaning it allows gases to pass through it easily. This property is advantageous in a crucible because it allows for the escape of gases that may be generated during high-temperature processes, such as melting or heat treatment. When a crucible is exposed to high temperatures, various chemical reactions may occur, leading to the production of gases such as carbon dioxide or carbon monoxide. If these gases are trapped within the crucible, they can create pressure build-up, causing the crucible to crack or even explode. However, with the gas permeability of graphite, these gases can escape through the crucible walls, preventing any potential damage. Moreover, the gas permeability of graphite also aids in the removal of impurities or volatile substances from the crucible. During certain processes, impurities or volatile materials may be present in the material being melted or treated. If these substances are not allowed to escape, they can contaminate the final product or affect the quality of the process. The gas permeability of graphite allows for the easy removal of these impurities, ensuring a cleaner and more efficient process. Overall, the gas permeability of graphite is essential for crucible performance as it enables the safe release of gases generated during high-temperature processes and facilitates the removal of impurities. By allowing gases to escape and preventing pressure build-up, graphite crucibles can maintain their structural integrity and durability. Additionally, the gas permeability of graphite promotes cleaner processes and ensures the quality of the final product.

Q: Can graphite crucibles be used for ceramic production?: No, graphite crucibles cannot be used for ceramic production. Ceramic production requires crucibles made from materials like alumina or zirconia, which can withstand high temperatures and provide a stable environment for the ceramic materials. Graphite crucibles are generally used for high-temperature applications involving metals and alloys.

Q: Are graphite crucibles suitable for melting alloys with low melting points?: Yes, graphite crucibles are suitable for melting alloys with low melting points. Graphite has a high melting point and excellent thermal conductivity, allowing it to withstand high temperatures and efficiently transfer heat to the alloy. Additionally, graphite is chemically inert and does not react with most metals, making it an ideal choice for melting low melting point alloys.

Q: What is the importance of carbon graphite as biological material?: As a conductive material of graphite in the electrical industry widely used as electrode, brush, carbon, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating etc.. The most widely application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as furnace head conducting material.

Q: Is it possible to repair a cracked or damaged graphite crucible?: Repairing a cracked or damaged graphite crucible is indeed possible, but the success of the repair depends on the extent and location of the damage. Typically, specialized graphite repair compounds or pastes are used to fix these crucibles. These compounds are applied to the cracked or damaged area, and then heated to cure and bond with the existing graphite material. Once repaired, the crucible can be used again for various high-temperature applications. It is worth mentioning that the repair process might not always succeed, particularly if the damage is severe or if the crucible is compromised in a critical area. In such cases, replacing the crucible becomes necessary to guarantee the process's integrity and safety.
