Application
The quality of high-alumina bricks varies significantly. The raw materials used differ, leading to a substantial 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℃.

High-strength alkali-resistant bricks
Alkali-resistant bricks are generally made from low-alumina clay bricks with an Al₂O₃ content of 25-30%, and are produced by adding silica, corundum, and appropriate additives to improve compressive strength.

Magnesium iron spinel bricks are a new generation of chromium-free alkaline refractory materials used in the firing zone of large rotary kilns. They utilize the characteristic of iron oxide solidifying in magnesium oxide, using high-purity spinel as raw material, and are formed into chromium-free and environmentally friendly products through high-temperature sintering.
