  • What is Special Shape Refractory Brick

    silica brick is made of quartz stone material, the content of SiO2 is above 93%,it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1620°C. SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk.
