Zirconia Mullite (Al₂O₃ + ZrO₂ + SiO₂)

A fused mullite composed of sizable needle-like mullite crystals containing co-precipitated monoclinic ZrO₂. Zirconia Mullite is characterized by high chemical purity, low thermal expansion, and high thermal shock resistance.
Zirconia mullite has a high resistance to environmental corrosion and a low coefficient of thermal expansion.
Chemical Composition

Al₂O₃= 45.80%, ZrO₂= 36.0% and SiO₂= 17.50%

Typical Applications

Fused zirconia mullite is an excellent material for refractory applications. It has applications that include ceramic pressure casting tubes, slide gates, nozzles, and special refractory parts for the glass industry.

Packaging Options

50 lb. or 50 lb. net wt. bags, steel drums, or bulk bags
