Detailed Product Description

graphite crucible is featured by fast heat conduction,long service life and low cost and the product finds good application

1.Garphite crucible can withstand the high temperature, an has good resistance to chemical erosions and thermal shock.

2.Graphite crucible is ideal for the melting of gold,silver,aluminum,copper and other metals and is also used as a tool for smelting jewelry.

Q:Can sintering rare earth fluorides be made of corundum crucibles?: Graphite crucibleIs the crucible, crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, refractory graphite crucible with different types of clinker with which is mainly used in smelting special alloy steel, nonferrous metals and alloy melting. Graphite crucibles are an integral part of refractories in terms of their properties and uses.

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:How do you prevent thermal shock in graphite crucibles?: To prevent thermal shock in graphite crucibles, there are several key steps that can be taken: 1. Preheating: Before using a graphite crucible, it is important to preheat it gradually. This can be done by placing the crucible in a furnace or kiln at a low temperature and slowly increasing the temperature over a period of time. This ensures that the crucible is uniformly heated and minimizes the risk of sudden temperature changes. 2. Avoiding rapid temperature changes: Graphite crucibles should be handled with care to prevent sudden temperature changes. They should not be exposed to extreme heat or cold, as this can cause thermal shock. Similarly, they should not be placed directly onto a hot surface or immersed in cold water immediately after use. 3. Proper handling and storage: Graphite crucibles should be stored in a dry and controlled environment to prevent moisture absorption, which can lead to thermal shock. Care should be taken when handling crucibles to avoid dropping or banging them against hard surfaces, as this can also cause thermal shock. 4. Adequate cooling: After use, graphite crucibles should be allowed to cool naturally and slowly. Placing a hot crucible in a cool environment or exposing it to a sudden temperature change can result in thermal shock. It is recommended to place the crucible on a non-conductive surface and allow it to cool at room temperature before further handling. 5. Regular inspection: Regularly inspecting graphite crucibles for any signs of damage or wear is crucial. Any cracks, chips, or other abnormalities should be addressed immediately, as they can weaken the crucible and increase the risk of thermal shock. If any damage is detected, it is advisable to replace the crucible to ensure its integrity during future use. By following these preventive measures, thermal shock in graphite crucibles can be minimized, resulting in improved durability and performance.

Q:Can a graphite crucible be used for melting thorium?: No, a graphite crucible cannot be used for melting thorium. Thorium has a high melting point, and its reactivity with graphite can cause contamination and reaction with the crucible material. A suitable crucible made from materials like ceramic or refractory metals should be used for melting thorium.

Q:Does a graphite crucible require any preheating before use?: Yes, a graphite crucible typically requires preheating before use. Preheating helps to remove any residual moisture or impurities present in the crucible, preventing them from affecting the purity of the materials being melted. Additionally, preheating can also help to prevent thermal shock and potential cracking of the crucible when exposed to high temperatures.

Q:Disadvantages of graphite crucibles: The graphite crucible is much better than the traditional crucible, to say the disadvantage is that the technical requirements are very high, and the life of the imported crucible and the domestic crucible is about 3:1.

Q:Can a graphite crucible be used for metal powder sintering?: Metal powder sintering can indeed use a graphite crucible. The reason why graphite crucibles are frequently employed in high-temperature scenarios, such as melting or sintering metals, is because of their exceptional thermal conductivity and resistance to thermal shock. The graphite material possesses the capability to endure the elevated temperatures required for metal powder sintering, thereby enabling efficient and effective sintering procedures. It is worth mentioning that the selection of a particular graphite crucible should be based on the type of metal being sintered, as certain metals might react with graphite at high temperatures. Moreover, it is imperative to handle and maintain the crucible properly in order to ensure its durability and performance throughout the sintering process.

Q:Can a graphite crucible be used for ceramic coating applications?: No, a graphite crucible cannot be used for ceramic coating applications. Ceramic coatings require high temperature and chemical resistance, which graphite does not possess. A crucible made from suitable materials such as alumina or zirconia would be more appropriate for ceramic coating applications.

Q:What magnetic material is sintered with large corundum crucible?: Corundum temperature limited, easily cracked at high temperature.

Q:Is it possible to repair a cracked graphite crucible?: Yes, it is possible to repair a cracked graphite crucible. One method is to use a high-temperature epoxy or adhesive specifically designed for graphite materials. The crucible should be thoroughly cleaned and dried before applying the adhesive. The cracked area can then be carefully aligned and the adhesive applied, following the manufacturer's instructions. After the adhesive has cured, the crucible should be tested for any leaks or weaknesses before using it again. However, it is important to note that the repaired crucible may not have the same strength and durability as a new one, so it should be used with caution and closely monitored during use to prevent any further damage. In some cases, it may be more practical and cost-effective to replace the crucible rather than attempting a repair.
