The Main Components Of Acidic Refractories

Acid refractory materials is mainly composed of silicon dioxide, commonly used silica brick and clay brick. Silica bricks containing silica over 94% of silica products, use silica, silica bricks and other raw materials, the strong acidic slag corrosion resistance, high refractoriness, size will not shrink after repeated burning, or even slightly inflated but its vulnerability to erosion of basic slag, poor resistance to thermal shock. Silica bricks mainly used in coke ovens, glass melting furnaces, acid furnace Thermal equipment. Clay bricks in refractory clay as raw material, alumina containing 30%~46%, are weakly acidic refractories, good thermal shock resistance, acid slag corrosion resistance, wide range of applications.
