Regarding the issue of failed startup with the 10X10 square silicon core
Thread Content
The success rate of starting up 10X10 square silicon cores is low; they often stick to the walls and the silicon cores bend – seek a solution. . .
If it had been German furnaces, then you would have followed purely German manufacturing techniques. If it’s a technique developed by you, then why use a square-shaped silicon core? Other cross-sections for silicon cores are also possible; it’s better to use a core with the smallest cross-section and thus the largest surface area
Should a silicon core be used with the smallest cross-section and the largest surface area? How should this be understood?
If there is no issue with the quality of the silicon core, then the problem might lie in the graphite fixture or the way it is installed :)
CVD refers to a vapor deposition reactor; if it’s possible to use square-shaped silicon cores, it’s better to opt for those with a triangular cross-section. The cross-sectional area determines the current capacity, while the surface area affects the production volume. Using triangular silicon cores results in too high costs
At present, most manufacturers in China have switched to using square silicon cores. Some manufacturers previously considered diamond-shaped silicon cores, but the requirements for the actual production process, as well as for subsequent processing and handling, are too high. One more question: GT Company displayed tubular silicon cores at the exhibition in Shanghai in May. Do you have any information on this? ]
I attended the exhibition. I’m aware of GT’s tubular silicon cores, which are designed primarily to address the issue of silicon core melting. In fact, high-frequency currents can be used to induce a skin effect in the silicon rods, resulting in better performance; the problem is that when operating conditions exceed 50, many components need to be customized
I have seen the tubular silicon cores used in GT; it’s likely that manufacturing a silicon core is more costly than manufacturing a silicon rod, and the inner surface of the core has machined patterns on it
What are the inner and outer diameters of the tubular silicon core? How long?
