Fused Zirconia Mullite

Fused Zirconia-Mullite, Fused Zirconia are highly recommended refractory raw materials.

Refractory Raw Material - Fused Zirconia Mullite, Fused Zirconia

Fused, high purity zirconia-mullite grain is produced by electric furnace fusion of alumina and zircon sand. During melting, the zircon and alumina react to yield a mixture of mullite and zirconia.

Applications of Fused Zirconia-Mullite

Fused Zirconia-Mullite is used in specialty product applications where a 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.
