A fused zircon mullite grain, high purity product produced in an electric arc furnace from Bayer alumina and zircon sand. It is composed of large needle-like mullite crystals containing co-precipitated monoclinic ZrO2.
Chemical Name: Zirconia-mullite
Chemical Formula: Al2O3 + ZrO2 + SiO2
Zirconia mullite powder, Zirconia aluminum silicate, Al2O3 + ZrO2 + SiO2, Fused zirconia mullite grain/ powder (Al2O3 + ZrO2 + SiO2), zirconia mullite grain, zirconia mullite powder, zirconia-mullite
Al2O3= 45.80%, ZrO2= 36.0% and SiO2= 17.50%
Various RF splits/granulations are available from 6/F to DC fines
Used in specialty product applications where high resistance to environmental corrosion and a low coefficient of thermal expansion are desirable properties. Applications include ceramic pressure casting tubes and refractory shapes requiring resistance to molten slag and molten glass.
