Advantages fused mullite

Porous ceramic fibers, adhesives, mullite precursor gel, mullite nanocrystals Introduction mullite has good properties, such as high melting point, a small expansion, thermal shock resistance, true specific gravity is low, creep resistance high and good chemical stability [] -21. From a porous material mullite fibers prepared with high porosity, lightweight, low thermal conductivity, high permeability, synthetic diamond non-brittle, etc., with a wide range of applications in the chemical, metallurgy, environmental protection and other areas will have great social and economic significance _3_. In fiber porous ceramic fibers rely architecture into the hole between the point of contact with the adhesive connection between the fibers, so the degree of solid adhesive bonding for excellent performance full of ceramic fiber base, end-use properties of the product from a decisive role. Considering the substrate used for forming porous mullite ceramic fibers, such as a binder with a sintered mullite crystalline phase, its crystalline phase cubic boron nitride and microstructure fibers with mullite and consistent with the same thermal expansion factor, after forming the porous ceramic having better performance. This paper used mullite fibers bonded with a porous ceramic mullite ceramics preparation and structure analysis.
