Saint-Gobain ZirPro is a global leader in the production of zirconium oxide powders. Offering the widest range of zirconia powders, ZirPro's portfolio includes monoclinic zirconia, yttria-stabilized zirconia (ranging from 3 mol% to 8 mol%), and pigmented zirconia. With two distinct manufacturing processes for zirconium oxide—thermal and chemical treatments of natural zirconium silicate—ZirPro produces powders with varying purities (from 97.0% to 99.9%), particle sizes (ranging from large 15µm particles to those under 1 micron), and reactivity (from 1m²/g to 25m²/g for certain chemically processed zirconia).
