Refractory Brick
Phosphate bricks, also known as phosphate-bonded high-alumina bricks, are high-alumina refractory products made from high-alumina bauxite clinker as aggregate and fine powder, with phosphate or aluminum phosphate as the binder, formed by semi-dry pressing and heat-treated at 400 to 600 degrees Celsius.

The quality of high-alumina bricks varies significantly, as different raw materials are used, resulting in a large difference in aluminum content. Ordinary high-alumina bricks have an aluminum content between 55% and 75%, a bulk density of 2.3 to 2.5, and a refractoriness of 1750-1790℃.

Anchor refractory bricks, also known as hanging bricks, are a type of refractory material used in industrial kilns. They are made by selecting high-quality raw materials, forming them through machine pressing or casting, and then sintering at high temperatures. Anchor bricks can be roughly divided into two types based on the material used: high-alumina and clay.
