Fused zirconia

The main production material of fused zirconia is high quality zircon sand, with carbon as reducing agent and a small amount of catalyst or stabilizer added. Such as cerium oxide or calcium carbonate. According to the melting point of zirconia and silica, the liquid phase is melted at the high temperature of the electric furnace to decompose and reduce the zircon, and finally zirconia and silicon micropowder are formed, and the zirconia is sprayed into a spherical shape by compressed air.
