Acid resistant bricks which are the anti-corrosion acid-resistant materials use quartz, feldspar, clay as main raw material, fired by the furnace at high temperature.

　　Acid resistant bricks for boiler chimney have excellent characteristics as follows:

　　1. Strong acid resistance;

　　2. High strength and wear resistance;

　　3. Low water absorption and low apparent porosity;

　　4. High corrosion and impact resistance;

　　5. High temperature resistant;

　　6. Good thermal shock resistance;

　　7. High mechanical strength.

　　Acid resistant bricks as power plant boiler refractories are mainly used for linings in the flue and chimney of thermal power plant.
