Ceramic fiber core

Alumina porcelain fiber is usually prepared by the high-tech "sol-gel" method. The specific steps include: soluble aluminum and silicon salt are made into colloidal solution with certain viscosity, and then fiber embryo is formed by high-speed centrifugal spinning, and then through dehydration, drying and medium-high temperature heat treatment and other processes of crystallization, and finally transformed into Al-Si alumina polycrystalline fiber ‌ MATERIAL : ZrO2 DENSITY  : 6 COLOR  : Black / White HRDNESS(Mohs scale) : 8.8 Bending Strength : 1200 MAX WORKING TEMPERATURE : 1050
