Semicorex C/C composite crucible support rods are the crucial supporting components engineered specially for single-crystal silicon manufacturing via Czochralski (CZ) growth method, which can stably support the C/C composite crucible and its internal molten silicon in the high-temperature thermal field. Choose Semicorex, choose the optimal supporting solutions for high-quality single-crystal silicon growth.
C/C composite crucible support rods are typically positioned in the lower region of high-temperature single crystal growth furnaces, forming a efficient and stable thermal field system for single-crystal silicon growth with these indispensable components, such as C/C crucible holders, C/C crucibles and C/C insulation cylinders. They can provide stable support for the crucible and internal molten silicon and achieve precise rotation and lifting of the crucible to meet the requirements of single-crystal silicon growth.
Since carbon-carbon composite boasts exceptional thermal resistance and thermal stability, Semicorex C/C composite crucible support rods can operate reliably at temperatures ranging from 1600 to 2200℃ and withstand rapid temperature changes without easily cracking or being damaged.
Carbon-carbon composites have high mechanical strength and elastic modulus, and their strength may even exceed that at room temperature under high-temperature operating conditions. It is precisely because of this reliable characteristic that Semicorex C/C composite crucible support rods can withstand the weight of the crucible and the large amount of silicon material inside without being prone to breakage.
Carbon-carbon composites have a lower density than conventional graphite materials, which means they are significantly lighter than conventional graphite materials. The overall weight of the Semicorex C/C composite crucible support rod can be greatly reduced thanks to this excellent lightweight structure, which brings convenience to equipment handling, replacement and maintenance.
During the growth of single-crystal silicon, silicon vapor can corrode components inside the single-crystal silicon growth furnace. Carbon-carbon composites exhibit excellent resistance to silicon vapor corrosion, which enables Semicorex C/C composite crucible support rods to maintain stable structural integrity and consistent performance under high-temperature and silicon vapor conditions.
