Properties
Acid proof brick are special ceramic bricks, use quartz, feldspar and clay as main raw material and sintered under high temperature furnace firing, which can resist high temperature, shock chilling and strong acid corrosion. They are widely used in reaction tanks, towers, troughs and stirring ponds in metallurgical and chemical processes.
