Lightweight high alumina bricks mainly made of bauxite (alumina ore) and other ingredients, usually containing 70% or more bauxite, mixed with a small amount of other ingredients (such as silica sand, clay). It has light weight and high refractory performance. The main component is high bauxite (Al2O2).

Features of Lightweight high alumina bricks：
Refractory: Lightweight high-alumina bricks have very high refractory temperatures, usually 1600°C to 1800°C, and are suitable for high-temperature environments.
Insulation: Due to the porous structure inside the brick body, it has excellent insulation properties, which can effectively reduce heat loss and improve the thermal efficiency of the furnace body.
Corrosion resistance: High-alumina bricks have strong corrosion resistance to molten metals, glass and other high-temperature media, and are suitable for harsh industrial environments.
Applications of lightweight high alumina bricks:
Electric arc furnaces: used in electric arc furnaces for steel and other metals. These furnaces need to withstand high temperatures and require good insulation to improve energy efficiency.
Glass melting furnaces: In glass production, lightweight high-alumina bricks are often used for furnace linings to ensure stability at high temperatures and reduce heat loss.
Ceramic kilns: used in kilns for high-temperature ceramic firing to help maintain the high temperature in the kiln while reducing energy consumption.
Non-ferrous metal melting furnaces: such as aluminum melting furnaces, lightweight high-alumina bricks can withstand high temperatures and can effectively insulate.
