Reduction furnace transformer production of polysilicon
Thread Content
What are the benefits of using a bell-type reduction furnace to produce polysilicon transformer production? The principle is that the pressure is low when the furnace is first started and then gradually increases the pressure. In terms of materials and production rate...

The benefits are obvious: It can increase the air intake volume of the mixed gas, shorten the production cycle, and increase the output of polysilicon. But the problem arises again: The "corn shape" that appears on the upper end of the silicon rod, especially the inner ring, is also serious. It also increases the risk of production.
Can you tell me in detail why the production cycle is shortened, why the output of polysilicon is increased, why it grows "corn-like", and why it increases the risk of production. · · · ·
