Silica fire bricks belonging to acid refractory bricks,have the excellent ability to resist acid slag and acid solution erosion. Ruitai Lianxin silica refractory bricks have good high temperature stability and high refractoriness under load about 1640-1680℃. Silica fire brick is an ideal refractory material for high-temperature furnace construction.
