REFRACTORYMULLITEFIBRE - Nature
Open Data Verified Data
The main components of mullite are A12 03 and Si02, and its chemical composition is: A1203 71. 8% and Si02 28.2%. With a rose red or blue when impurities. Orthorhombic crystallization into columnar or needle-like crystals. The relative density is 3. 03 and the melting point is 1910 ℃. The strength does not decrease at high temperature, the thermal expansion coefficient is low (5 × 10-6/K), and the thermal shock resistance, corrosion resistance and creep resistance are good. Its high temperature creep resistance and thermal shock resistance stability is good, excellent electrical insulation and chemical stability, high temperature strength does not decrease, good thermal shock resistance.

| purpose | is the main component of clay brick, alumina brick and porcelain, etc, fillers for pigments and paints. Rubber, plastic, printing, Ink. |
| production method | 1. Mullite method: a certain proportion of alumina and silica are fully mixed, heated and melted at high temperature, and prepared by cooling and crushing. 2. Mullite fiber preparation method: Alumina aluminum powder and silica are proportionally mixed into colloidal solution, and inorganic acid and alcohol and other stabilizers are added, and then spinning is carried out. After spinning and drying, sintering is carried out at a temperature above 800 ℃, mullite fiber. 3. Solid solution method. A certain proportion of aluminum oxide and silicon dioxide are thoroughly mixed, heated at high temperature to solid melt, and then cooled and crushed to obtain. It can be obtained by sol-gel method. |
