Corundum Zirconia Crucibles
Product Description
Corundum Zirconia Crucibles are mainly made of alumina. Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses a high melting point, strong hardness, and good chemical stability, making the products good material to withstand high temperature and chemical corrosion. Alumina Crucibles are available in various sizes and shapes, we can meet any customized production requirements. The covers of Corundum Zirconia Crucibles are available upon request for high form and cylindrical crucibles.
Product Advantages
● High form porcelain crucible is glazed inside and out, except for the outside bottom surface and rim
● Thermally shock-resistant;
