(1) The material of the crucibleWhen preparing cast polysilicon, in the process of raw material melting and crystalline silicon crystallization, the silicon melt and the quartz crucible are in contact for a long time, which will cause viscous effect. Due to the different thermal expansion coefficients of the two, the volume of silicon increases by … Read More
