High purity zircon, fused AZS grains and stabilized Zirconia are among the inputs for a range of high performance Zircon (upto 67% ZrO2 content) and Zircon Mullite refractories. The entire range of bonded ZrO2 containing refractories have been indigenously developed and are distinguished by their excellent alkali resistance in regenerator and melter applications in glass plants. Blocks and tiles can also be supplied in these qualities.
