Zirconia fused alumina Zirconia fused alumina is produced in a high temperature electrical arc furnace by fusing zirconium quartz sand. It is characterized by hard and dense structure, high toughness and good thermal-stability. It is suitable for heavy grinding and making high grade refractory materials etc. Typical Chemical Analysis (%): Hardness True Density Chemical composition (%) Moh"s g/cm3 AL2O3 ZrO2 TiO2 SiO2 9 4.2 .*8.*0 *0.****7.0 <3.*0 <1.*0 8. Fused Mullite Fused Mullite is made from pure quartz and industrial alumina in super-large electric arc furnace. It has a high content of mullite crystals which has a lot of advantages such as high melting point, excellent thermal stability, low reversible thermal expansion and resistance to thermal shock and chemical corrosion at high temperature. It is widely used as lining brick glass body kiln and large hot wind furnace in iron-making blast furnace, as well as in ceramic kiln, petroleum and chemistry.
