Rongsheng Refractory Supply Alumina Carbon Bricks With Superior Performance For High-Temperature Kilns

Composition and Materials of Alumina Carbon Fire Bricks

Alumina Carbon Bricks are primarily composed of high-purity alumina (Al₂O₃) and carbonaceous materials such as graphite. The typical composition includes:

• Alumina (Al₂O₃): 60-85%
• Carbon: 5-20%
• Binders and Additives: Various organic and inorganic materials to enhance properties

The blend of these materials results in bricks that offer superior performance in extreme conditions.
