> The main chemical component of the quartz crucible is silica.
> Quartz crucible has good thermal stability and can be heated directly on the flame.
> Quartz crucibles, like glassware, are easy to break, so be careful when using them.
> Quartz crucible can use potassium hydrogen sulfate (sodium), sodium thiosulfate (baked at 212 degrees Celsius) as a flux, and the melting temperature must not exceed 800 degrees Celsius.

Translucent quartz crucible is an essential basic material for drawing large-diameter single crystal silicon and developing large-scale integrated circuits. Quartz crucibles are mainly used in semiconductor, photovoltaic and other fields. Due to the high degree of product precision and rapid technological development in the photovoltaic industry, the requirements for the purity and accuracy of quartz crucibles are becoming increasingly stringent.
