Alumina bricks are made from bauxite of super quality, bonding chamotte and additives. The main Al203 content is 48%-99%. The advantages of high alumina bricks are high refractoriness, anti alkaline/acid erosions, good strength under high temperature and good thermal shock resistance. High alumina bricks were widely accepted in thermal equipment of metallurgy, petroleum, chemical industry, construction materials, machinery and militaries etc.
