Zirconia mullite
Introduction

Fused zirconia mullite is made by fusing certain percentage of high purity aluminum oxide and

zircon sand in electrical arc furnace.

 

Zirconia mullite character :

AZSL 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.

Applications:

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