Refractory Silica Brick

Refractory Silica Brick

Silica brick is made of quartz stone material, the content of SiO2 is above 93%. It is of good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C, RUL is beyond 1620°C.

Advantage:

  • Good thermal conductivity.
  • High refractoriness under load.
  • Good creep resistance.
  • High refractoriness.
