Isostatic graphite has the following excellent properties:
1. It has good heat resistance. In an inert atmosphere, its mechanical strength increases with the increase of temperature, reaching the maximum value at about 2500°C;
2. Compared with ordinary graphite, it has good uniformity and fine and dense structure;
3. Low thermal expansion coefficient and good thermal shock resistance;
4. Isotropic, consistent performance in all directions;
5. It has strong chemical corrosion resistance and can withstand the penetration and erosion of molten metal and glass;
6. Good electrical conductivity and thermal conductivity;
7. It has excellent machining performance and can be processed into almost any shape of items.
Isostatic graphite is widely used in the production of CZ single crystal Czochralski furnace thermal field graphite components (crucible, heater, guide tube, insulation cover, etc.), polycrystalline silicon smelting furnace, heaters, crucibles and other components for compound semiconductor manufacturing. Rocket ignition pole, excitation pole, nozzle and rudder plate, nuclear reactor core structure, electrodes for electrical discharge machining, graphite crystallizer for continuous casting metal, etc.
As monocrystalline and polycrystalline silicon products develop towards larger sizes, higher performance, and better quality, there are also higher requirements for isostatic graphite, which requires larger specifications, higher strength, and higher purity. ability to develop.
The downstream industries of the special graphite industry include metallurgy, chemical industry, machinery, electronics, photovoltaics, new energy, aerospace, military industry, nuclear engineering and other industries.
