Zirconia Powders

Saint-Gobain ZirPro is a world leader in the manufacturing of zirconium oxide powders, for more than 30 years.



Zirconium Oxide (Zirconia) Powders – ZrO2

 

Three main manufacturing processes:

  • Fusion and reduction of zirconium silicate (zircon sand) : fused zirconias (ZF)
  • Original process based on zircon sand fusion and chemical treatments : thermal zirconias (CC, CS)
  • Chemical processes from zirconium oxychloride (ZOC) : chemical zirconias (CZ, CZE, CYZ) and zirconium hydrates or hydroxides (ZHO).

 

This gives Saint-Gobain ZirPro a unique and strong position, for the development and the manufacturing of a complete range of zirconium oxides, in terms of:

  • Chemical purity: from 98.5% (fused and thermal zirconias) to 99.95% (chemical zirconias)
  • Particle size distribution: the mean particle size of the zirconia powders (D50) vary from several hundreds of microns to less than 1 micron (typically 0.3 micron).
  • Specific surface area (or “reactivity”): the reactivity vary from 1m²/g for the fused zirconias to 250 m²/g for the zirconium hydroxides.
  • Dopants: some dopants can be added to the zirconium oxide powders in order to modify or improve:

             - The crystallographic structure: magnesium oxide (MgO) or yttrium oxide (Y2O3) are added to the zirconia, in order

                to stabilize the tetragonal and/or cubic phase. Without any dopant, the zirconia has a monoclinic structure

             - The surface properties of the powders, specific surface area, porosity, acidity

             - The colour of the final ceramic : special coloured zirconias have been developed, in order to obtained coloured

               dense ceramics.

Applications

 

For almost every application using zirconium oxide, Saint-Gobain ZirPro can propose or develop a solution adapted to your needs:

  • Zirconium silicate based ceramic pigments, used in tiles, glazes, sanitaryware
  • Refractory ceramics, molten metal filters
  • Glass and gemstones composition
  • Electronic ceramics: PZT, multi layer ceramic condenser (MLCC), Dielectric components
  • Thermal spray powders (TSP), thermal barrier coatings (TBC)
  • Structural ceramics for the industry: valve components, wear & abrasion resistant components, milling medias,…
  • Dental ceramics
  • Consumer and decorative ceramics: watches, knifes, mobile phones,…
  • Ionic conductive ceramics: gaz sensors, solid oxide fuel celles (SOFC)
  • Catalysis : petrochemical and automotive catalysis
