Silicon core installation time and furnace startup time
Thread Content
Once a silicon core is installed in the furnace, how long can it go without the furnace being started before the silicon core oxidizes, thereby affecting the quality of the polycrystalline silicon? If it is nitrogen-sealed, how long after not starting the furnace does it need to be refilled? How long should the time taken to install the silicon core be? I hope everyone will share their ideas! Not very grateful!
It’s fine to maintain pressure with nitrogen or to keep blowing nitrogen; leaving it for a couple of days is no problem
