FUSED ZIRCONIO MULLITE

1. Description:

Fused zirconia mullite is made by fusing certain percentage of high purity aluminum oxide and zircon sand in electrical arc furnace. DRSL characters small coefficient of thermal expansion, high strength, good thermal shock resistance and strong resistance to slag. It can well improve the anti-corrosive ability of the refractory products and enhance refractories wear resistance.

2. Applications:

DRSL is used for making zirconia mullite refractory bricks, Al2O3-ZrO2-C sliding plate and long nozzle service for metallurgical industry. DRSL is also widely used in glass kiln and making castable reractories.
