High Purity Alumina Insulating Materials

    The products is featured with high purity of alumina(Al2O3> 99%), high strength,low density, low thermal conductivity, low reheating linear change, excellent thermal shock resistance which makes the products without spalling and dropping during use, and long service life. It is able to provide a clean sintering environment under 1800℃, and can be used as the lining materials for transparent ceramic sintering furnace, hydrogen furnace and crystal growth furnaces.
