Alumina fiber is one of the latest ultra-light high-temperature insulation materials at home and abroad. It uses high-tech "sol-gel" method to make soluble aluminum and silicon salt into colloidal solution with a certain viscosity. The filaments are centrifuged into fiber embryos, and then transformed into Al-Si alumina polycrystalline fibers by dehydration, drying and medium-high temperature heat treatment and crystallization. The main crystal phases are mainly corundum phase and a small amount of mullite phase.
