Silica Bricks are made of quartz stone material.The content of SiO2 is more than 94%.Silica fire bricks belonging to acid refractory bricks,have the exnt ability to resist acid slag and acid solution erosion.Silica refractory bricks have good high temperature stability and high refractoriness under load about 1640-1680â. It is an ideal refractory material for high-temperature furnace construction.As a professional silica bricks manufacturer, we have exported silica refractory bricks to more than 30 countries.
