Top 10 mullite brick Manufacturers in the world 2025

Introduction to Mullite Brick

Mullite brick is a high - performance refractory material with excellent thermal and mechanical properties. It is mainly composed of mullite crystals, which endow it with high refractoriness, good thermal shock resistance, and low thermal conductivity. These characteristics make mullite bricks widely used in various high - temperature industrial applications, such as steelmaking, glass manufacturing, cement production, and non - ferrous metal smelting. In the steel industry, for example, mullite bricks are used in the lining of furnaces to withstand the extremely high temperatures and corrosive environments. In glass kilns, they help maintain the stability of the kiln structure and ensure the quality of glass production.
