Question:

How much fire resistance is quartz crucible?

How much fire resistance is quartz crucible?

Answer:

The long-term use of the crucible temperature is 1100 degrees, but pulling when the stone is outside, so can be used for a long time. The crucible will deform about 1300 degrees. 1100 degrees without deformation.
The quartz glass crucible is usually used for the production of monocrystalline silicon, and the production temperature of single crystal is 1450 degrees
It depends on the raw material used in your crucible. It is usually above more than 1100 degrees, but it must be guaranteed to not be crystallized
