Product Description
Acid proof brick is the main component of silicon dioxide, it under the high temperature roasting formed a lot of mullite, which is a acid high performance material.
Due to the close of acidproof brick structure, bibulous rate is small, so at room temperature is resistant to any concentration of alkaline medium. Not resistant to high temperature of molten alkali. Acid proof brick containing silica 70% above, by sintering.
