Fused Zirconia

Description

Fused zirconia is produced from zircon sand, which is one of the minerals found in heavy mineral sand sedimentary deposits derived from the alteration of granitic or alkaline rocks. In order to produce fused zirconia, 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.

Unique Characteristics

Good mechanical properties and stability at high temperatures
Superior thermal resistance and corrosion resistance
Consistency of its physical and chemical characteristics
High chemical inertness
FUSED ZIRCONIA APPLICATIONS
Fused Zirconia has many unique and complex properties which make it suitable for a variety of different high end refractory, ceramic, and electronics applications.

Application

Refractories used in the production of steel and glass products
Manufacture of heat resistant refractory materials and shapes
Fused cast brick for glass furnaces
Special Refractories - slide gates, long nozzles and crucibles
Ceramic fillters - foundry casting
Ceramic colours and glazes
Fused Zirconia powders are used in the preparation of ceramic pigments which form the basis of most colourants used for tableware, sanitary ware, and floor and wall tiles. They resist high temperature firing processes and the unique crystal structure of Zirconia enables it to make a wide selection of coloured stains ready for application to ceramic tiles.

Other Applications
Friction products in the auto industry - brake linings
Welding rods
Technical ceramics and electronics - setter plates and saggers
Zirconium Metals and Alloys
Zirconium Sponge for structural parts for reactors in the Nuclear Industry
