Microsilica for Alumina–Mullite Ceramic Composites
Mullite(3Al2O3.2SiO2) is a ceramic material with high temperature stability, high temperature creep resistance, high temperature mechanical properties and excellent chemical stability, low temperature expansion and good electrical insulation. As high-temperature refractory material and composite materials, mullite is widely used in such fields as national defense, industry and civil use. The…
