Silica bricks belong to acid refractory fire brick with above 94% high quality SiO2 content materials. The refractoriness of raw silica materials increases with increasing SiO2 content. Tridymite, ashlar, and vitric are minerals found in silica bricks and were created at high temperatures. Silica refractory brick in Topower Refractory has high stability under high temperature (1620~1670ºC)and pressure stresses.
Features Of Silica brick
Super higher cold crush strength character
Higher temperate resistant with good refractoriness
Lower impurity content
Excellent resistance in slag abrasion
No shrink in burn repeatedly.
