Jan. 01, 1970

As we all know that the refractory brick can be divided into Fire Brick,High Alumina Brick, also there are some other refractory products like Ceramic fiber board.Do you know waht is the Acid Resistance Brick?

Acid Resistance Brick usually refers to SiO2 and other high content of refractory oxide. Such as siliceous, semi-siliceous, fused silica and remelt fused silica refractories. Different countries have different SiO2 content. The lower limit is usually between 65% and 80%. [1] It is mainly composed of silicic acid or aluminum silicate, which is a refractory material that easily generates salts under the action of high temperature and alkali.
