This post was last edited by zjiris on 2009-9-17 19:45. Is silicon powder used for sealing? What is used to control the feeding of silicon powder? How many points are there for the continuous and batch feeding methods?

Intermittent feeding, no sealing required. It’s okay to heat the silicon powder silo with N, but it can easily affect the temperature of the synthesis furnace.

Of course, continuous feeding is also possible, but more equipment is required apart from the synthesis furnace

Material tank, drying bin, intermittent feeding. No sealing required, dual-valve discharge

Silicon powder dryer; the metering tank is fed via a feeding valve

If it’s not sealed, moisture will definitely get in. So how can we ensure that the feed is sealed?
