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 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.

Q: Can graphite crucibles be used for semiconductor manufacturing?: No, graphite crucibles cannot be used for semiconductor manufacturing.

Q: Procedures for operating high temperature furnaces: A, the graphite crucible is placed on the platform of the conveying cart, and the position is determined by using the spacing bar.B, pull out the stop lever, switch the car to IN, and then operate the UP - FORWARD - BACK - DOWN, the crucible into the furnace, and determine the delivery vehicle will arrive at the initial position.C, Mount graphite cover plate, tighten the graphite bolt, close the door

Q: What are the components of a pencil core?: Graphite (graphite) is a mineral name, usually produced in metamorphic rocks and is coal or carbonaceous rock (or sediment) formed by regional metamorphism or magmatic intrusion.

Q: Does a graphite crucible require any special handling during transportation?: Yes, a graphite crucible requires special handling during transportation. Graphite is a brittle material that can easily crack or break if subjected to excessive pressure or impact. To ensure the safe transportation of a graphite crucible, it should be packaged securely in a padded or cushioned container to protect it from any potential damage. Additionally, it is important to handle the crucible with care, avoiding any rough or sudden movements that could cause it to hit against other objects or surfaces. By taking these precautions, the risk of damage to the graphite crucible during transportation can be minimized.

Q: Can graphite crucibles be used for melting composite materials?: Indeed, composite materials can be melted using graphite crucibles. Renowned for their elevated melting point and excellent thermal conductivity, graphite crucibles are well-suited for the fusion of various materials, including composite ones. Moreover, their resistance to chemical reactions renders them optimal for managing and confining composite materials while undergoing the melting procedure. Nevertheless, it is crucial to thoroughly assess the composite material's specific composition and melting point to guarantee its compatibility with the graphite crucible.

Q: How do you prevent graphite crucibles from cracking during cooling?: To prevent graphite crucibles from cracking during cooling, it is important to follow these measures: 1. Gradual cooling: Avoid exposing the crucibles to abrupt temperature changes. Allow them to cool down slowly and naturally, as rapid cooling can cause thermal shock and lead to cracking. 2. Use insulating materials: Place the crucibles on an insulating pad or use insulating materials like ceramic fiber blankets or boards. These materials help to regulate temperature and reduce heat transfer, minimizing the risk of cracking. 3. Avoid direct contact with water: Graphite crucibles should not be directly exposed to water or other coolants immediately after use. Allow them to cool down at room temperature first, and then carefully clean them without sudden temperature changes. 4. Handle with care: When moving or handling hot crucibles, ensure proper support and use heat-resistant gloves or tongs. Sudden impacts or mishandling can cause stress and lead to cracking. 5. Preheat and anneal: Before initial use, it is recommended to preheat new crucibles gradually to remove any residual moisture. Similarly, annealing crucibles periodically at lower temperatures can relieve internal stress, reducing the chances of cracking during cooling. By following these precautions, one can minimize the risk of graphite crucible cracking and extend their lifespan.

Q: Can a graphite crucible be used for non-ferrous metals?: Yes, a graphite crucible can be used for non-ferrous metals. Graphite crucibles are commonly used in foundries and laboratories for melting and casting non-ferrous metals such as gold, silver, copper, aluminum, and zinc. Graphite is an excellent material for high-temperature applications due to its high thermal conductivity and high melting point. It can withstand the intense heat required to melt non-ferrous metals without melting or reacting chemically with the molten metal. Additionally, graphite crucibles have good resistance to thermal shock and are relatively easy to handle and clean. Therefore, they are a preferred choice for melting non-ferrous metals in various industries.

Q: What are the considerations for selecting a crucible tongs for handling graphite crucibles?: When selecting crucible tongs for handling graphite crucibles, there are a few important considerations to keep in mind. Firstly, it is crucial to choose tongs that are specifically designed for graphite crucibles. Graphite is a brittle material and can be easily damaged or broken if not handled properly. Therefore, the tongs should have a design that provides a secure grip without exerting excessive pressure on the crucible. Secondly, the length and size of the tongs should be appropriate for the size and weight of the graphite crucible. This ensures that the tongs provide sufficient leverage and control while handling the crucible, minimizing the risk of accidents or mishandling. Additionally, the material of the tongs should be carefully considered. It is advisable to opt for tongs made of heat-resistant materials like stainless steel or nickel alloy, as they can withstand high temperatures without warping or corroding. This is particularly important when working with graphite crucibles, as they are often used in high-temperature applications such as metal casting or melting. Lastly, ergonomics and comfort should not be overlooked. The tongs should have a comfortable grip that allows for easy and precise handling, reducing the strain on the operator's hand and wrist. This is especially important during prolonged or repetitive usage. Overall, selecting the right crucible tongs for handling graphite crucibles involves considering the design, size, material, and ergonomics to ensure safe and efficient handling of the crucibles.

Q: Can a graphite crucible be used for melting non-metallic materials?: Yes, a graphite crucible can be used for melting non-metallic materials. Graphite has a high melting point and excellent thermal conductivity, making it suitable for melting various non-metallic substances such as glass, ceramics, and certain minerals.
