We supply a full series of Fused Zirconia products, product
includes Fused Monoclinic Zirconia, Fused Calcium Stabilized
Zirconia, Fused Magnesia Stabilized Zirconia and Fused Yttria
Stabilized Zirconia.
Fused Zirconia is produced in electric arc furnace at temperatures
in excess of 2700C. Zirconia has excellent thermal shock resistance
and is very thermally stable to high temperatures, has low thermal
conductivity, and is chemistry insert. Zirconia is also not wetted
by many metals and glasses and is therefore an excellent contact
material in the existence of slags. Fused Zirconia is used in steel
and glass contact refractories, investment casting as shell
building material, as wear resistant coatings, thermal barrier
coatings, and other applications that require high temperature, and
frequent thermal cycling.
Applications of Fused Zirconia Powders:
- Zirconium silicate based ceramic pigments, used in tiles, glazes,
sanitary ware
- Refractory ceramics, molten metal filters
- Glass and gemstones composition
- Electronic ceramics: PZT, multi-layer ceramic capacitor (MLCC),
Dielectric components
- Thermal spray powders (TSP), EBPVD ingots for thermal barrier
coatings (TBC)
- Structural ceramics for the industry: valve components, wear &
abrasion resistant components, milling medias,bearings, cutting
tools, …
- Ferrules and sleeves for optical fiber connectors
- Consumer and decorative ceramics: watches, knives, mobile phone
part,…
- Dental ceramics
- Ionic conductive ceramics: gaz sensors, solid oxide fuel celles
