High Alumina Brick-Level 1

High alumina brick is a kind of refractory material. The main component of this refractory brick is Al2O3. If the Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries stipulate that the lower limit of Al2O3 content for high-aluminum refractory materials is 42%. In China, high alumina bricks are usually divided into three grades according to their Al2O3 content: Grade I - Al2O3 content >75%; Grade II - Al2O3 content 60-75%; Grade III - Al2O3 content 48-60%.

Phosphate high alumina brick, also known as phosphate-bonded high alumina brick or chemically bonded high alumina brick, is a type of refractory brick that is made by combining high-purity alumina with a phosphate-based binder. The binder reacts with the alumina at elevated temperatures to form a chemically bonded matrix, providing cohesion and strength to the brick.
