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: Can graphite crucibles be used for both melting and casting?: Both melting and casting can be done using graphite crucibles. Graphite is well-known for its exceptional heat resistance and high melting point, making it an ideal choice for containing molten metals during the melting process. Furthermore, graphite crucibles possess excellent thermal conductivity, enabling efficient heat transfer and uniform heating of the molten metal. Once the metal has melted, the graphite crucible can also serve as a casting tool. The molten metal can be poured directly from the crucible into a mold, allowing for the creation of various shapes and forms. Graphite crucibles are typically durable and can withstand multiple heating and cooling cycles, making them suitable for both melting and casting procedures. However, it is essential to acknowledge that graphite crucibles may not be suitable for all types of metals. Some reactive or corrosive metals can react with graphite at high temperatures, leading to contamination of the molten metal. In such cases, alternative crucible materials, such as ceramic or refractory metals, may be more appropriate.

Q: Can graphite crucibles be used for powder metallurgy?: Indeed, powder metallurgy can utilize graphite crucibles. Graphite proves to be an exceptional substance for applications involving high temperatures, and it is frequently employed in powder metallurgy procedures. Graphite crucibles possess a melting point that is notably high and exhibit outstanding thermal conductivity, rendering them perfectly suited for the process of melting and retaining metal powders during sintering or melting operations. Furthermore, graphite crucibles demonstrate commendable chemical resistance, enabling them to endure the corrosive impact of specific metal powders. In summary, graphite crucibles present themselves as a dependable and efficient option for applications within the realm of powder metallurgy.

Q: Does a graphite crucible require any special handling during transportation?: During transportation, it is imperative to handle a graphite crucible with special care. Graphite, being a brittle material, can easily crack or break when exposed to excessive pressure or impact. To guarantee its safe transportation, it is necessary to securely package the crucible in a cushioned container to shield it from any potential harm. Furthermore, it is crucial to handle the crucible delicately, avoiding any abrupt or rough movements that may cause it to collide with other objects or surfaces. By adhering to these measures, the likelihood of damage to the graphite crucible during transportation can be significantly reduced.

Q: Are graphite crucibles suitable for melting radioactive materials?: Graphite crucibles, unfortunately, do not possess the suitability for melting radioactive materials. Typically, these crucibles find their application in the melting of non-reactive substances like metals and alloys. However, they lack the necessary design to handle radioactive materials. It is crucial to recognize that radioactive materials have the potential to emit harmful radiation, resulting in the potential for reactions with or contamination of the graphite crucible. Therefore, it becomes imperative to employ special crucibles manufactured from radiation-resistant materials such as ceramics or refractory metals when melting radioactive materials. This precautionary measure guarantees safety and prevents any form of contamination.

Q: Can a graphite crucible be used for melting californium?: Using a graphite crucible to melt californium is not possible. This is because californium is an extremely reactive and radioactive element, necessitating specialized equipment for its handling and melting. While graphite crucibles are commonly utilized for melting and casting various metals and alloys due to their high melting point and heat resistance, californium possesses distinct properties and chemical behavior. Consequently, a crucible composed of a material capable of withstanding its intense levels of radioactivity and reactivity is required for californium handling.

Q: How does the thermal stability of graphite affect the performance of a crucible?: The thermal stability of graphite greatly affects the performance of a crucible. Graphite is known for its high melting point and excellent resistance to thermal shock, making it a suitable material for crucibles. Its ability to withstand high temperatures without deforming or cracking ensures that the crucible maintains its shape and integrity during the intense heat of various industrial processes such as melting metals or glass. Additionally, graphite's thermal stability helps in evenly distributing heat within the crucible, allowing for efficient and consistent heat transfer. Overall, the thermal stability of graphite plays a crucial role in ensuring the durability and performance of a crucible in extreme temperature conditions.

Q: Can graphite crucibles be used with induction melting furnaces?: Yes, graphite crucibles can be used with induction melting furnaces. Graphite crucibles have excellent thermal conductivity and high melting points, making them suitable for use in induction melting furnaces. The high conductivity allows for efficient heat transfer, ensuring uniform heating of the metal being melted. Additionally, graphite crucibles have good resistance to thermal shock, which is important in the intense heat environment of an induction melting furnace. However, it is essential to ensure that the graphite crucible is compatible with the specific metal being melted to avoid any chemical reactions or contamination.

Q: How much temperature does a graphite crucible hold?: Mainly depends on the use of working conditions, the use of air, then more than 600 degrees Celsius will begin to be oxidized, and the service life will not be long.

Q: Can a graphite crucible be used for silver melting?: Yes, a graphite crucible can be used for silver melting. Graphite is an excellent heat conductor and can withstand the high temperatures required for melting silver. It is also chemically inert, meaning it does not react with silver or contaminate the metal during the melting process.

Q: How do you prevent graphite crucibles from thermal shock during use?: To prevent graphite crucibles from thermal shock during use, it is important to preheat them gradually before exposure to high temperatures. This can be done by placing the crucible inside the furnace and slowly increasing the temperature over a period of time. Additionally, it is crucial to avoid sudden temperature changes, such as placing a hot crucible directly on a cold surface or immersing it in cold water immediately after use. By following these precautions, the risk of thermal shock and potential damage to the crucible can be minimized.
