Fused Zirconia
The production of fused zirconia involves reacting zircon at 2,800 degrees Celsius in an electric arc furnace to form molten zirconia and silica. The silica is driven off and collected separately as a silica fume, while the zirconia is formed into a coarse granular material.
Fused Zirconia Range
The fused Zirconia is graded, crushed, sized and available in five purities up to 99.3 wt% ZrO2. All grades are available in either milled or unmilled sizes depending on customer requirements. Standard unmilled sizes are <0.5mm or <10 mm while milled sizes are 6um, 4.5um and 3um. Custom sizes are also available upon request.
A range of low uranium and thorium (<500ppm combined) products are also produced.
Our Fused Zirconia is monoclinic in shape with typical characteristics such as:
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 Application
Fused Zirconia has many unique and complex properties which make it suitable for a variety of different high end refractory, ceramic and abrasive applications.
Fused Zirconia is used in the following industries and areas:
- 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 filters – foundry casting
- Ceramic colours and glazes
- Other Applications
Friction products in the auto industry – brake linings.
Technical ceramics and electronics – setter plates and saggers.
Zirconium Metals and Alloys.
Zirconium Sponge for structural parts for reactors in the Nuclear Industry.
