The production of fused zirconia includes
reacting zircon at 2,800 degrees Celsius in an electric arc heater to form
molten zirconia & silica. The silica is driven off and composed separately
as silica fume, while the zirconia is designed into a coarse granular material.
Fused zirconia ranges
The fused Zirconia is graded, crumpled,
sized, and available in purities up to 99 wt.% ZrO2. All grades are obtainable
in either milled or unfilled sizes depending on customer requirements. Standard
unfilled sizes are < 0.5mm or < 10 mm while milled sizes are 6um, and
3um. Custom sizes are also obtainable upon request. A range of low uranium &
thorium which is <500ppm combined products are also produced.
Characters of our Fused
zirconia
Our Fused
zirconia is monoclinic in shape with distinctive characteristics
such as:
Good mechanical properties &
stability at higher temperatures
Greater thermal resistance &
corrosion resistance
Consistency of the physical &
chemical characteristics
Higher chemical inertness
Applications of Fused zirconia
Fused Zirconia has many exclusive
and complex properties which make it appropriate for a variety of different higher-end
refractory and abrasive applications.
Fused Zirconia is also used in
the subsequent industries and areas:
Refractories that are used in the
production of steel & glass products
Manufacture of heat-resistant
materials and shapes
Fused cast brick for the glass
furnaces
In special Refractories like
slide gates, long nozzles, and also crucibles
In Ceramic filters like foundry
casting
In Ceramic colours & glazes
In Friction products in the auto
industry like brake linings
In Zirconium Metals & Alloys
In Zirconium Sponge for
structural parts in the Nuclear Industry
Fused Calcia Stabilized Zirconia is
substantial for use in the manufacture of slide gate furnace lining used in the
continuous casting of steel.
