Fused Zirconia, (ZrO2) is produced from zircon sand. Zircon sand is reduced and fused in an electric arc furnace under a temperature exceeding 2,600°C. Once the fused zirconia has cooled down, it is crushed and sized to fit required specifications.
Fused Zirconia has many unique and complex properties which make it suitable for a variety of different high end refractory, ceramic and abrasive applications. It is used in the following industries and areas: manufacture of heat resistant refractory materials and shapes, fused cast bricks for glass furnaces, specialty refractories (slide gates, long nozzles and crucibles), ceramic filters – foundry casting, friction products (brake linings) in the auto industry, technical ceramics and electronics (setter plates and saggers), zirconium metals and alloys.
