The special graphite products such as graphite heaters, graphite crucibles, and graphite guide rings for the crystal growth furnace produced by Huajin New Materials can meet the usage requirements of different components.
High density, high strength, dense structure, homogeneous material, batch stability, and excellent resistance to silicone vapor corrosion.
Special graphite materials play a key role in silicon carbide crystal growth furnaces.
1、It should have excellent high temperature resistance and be able to withstand extremely high temperatures during the crystal growth process while maintaining stability, ensuring the reliability of the crystal growth environment.
2、It should have high thermal conductivity, which can effectively conduct heat and help maintain the uniformity of temperature inside the furnace, which is crucial for the quality and consistency of crystal growth.
3、The special graphite material used in crystal growth furnaces also has good chemical stability, is not easily reactive with other substances, and can maintain its properties under complex crystal growth conditions.
4、It should have high mechanical strength and can withstand various stresses and pressures during the operation of the crystal growth furnace, ensuring the long-term stable operation of the equipment.
The use of high-quality special graphite materials in the growth of silicon carbide crystals helps to improve the growth efficiency and yield of crystals, providing important support for the development of the silicon carbide industry.
