High alumina bricks are primarily made of alumina (Al2O3), which is a refractory material known for its exceptional resistance to heat and chemical corrosion. These bricks are classified based on their alumina content, typically ranging from 48% to 95%. The higher the alumina content, the better the thermal resistance and refractoriness of the bricks. Chemical Composition of High Alumina Bricks Apart from alumina, high alumina bricks contain several other materials that contribute to their overall properties. The chemical composition can vary depending on the specific requirements of the application, but the following ingredients are commonly found in high alumina bricks: 1. Alumina (Al2O3) Alumina is the primary component of high alumina bricks, constituting the majority of their chemical composition. It provides the bricks with exceptional thermal resistance, high refractoriness, and resistance to chemical corrosion. The alumina content in high alumina bricks typically ranges from 48...

Ceramic fiber is a versatile and high-performance material known for its excellent thermal insulation properties.
