Transformation-toughened 3Y-TZP structural zirconia parts and ultra-refractory YSZ/Mg-PSZ crucibles, setter plates, and tubes rated up to 2,100 °C.
Zirconium dioxide stabilized with yttria (3Y-TZP or 8YSZ) or magnesia (Mg-PSZ) bridges two demanding regimes: at room to moderate temperatures, fine-grain 3Y-TZP delivers the highest fracture toughness (~8–10 MPa·m½) and flexural strength (>900 MPa) of any oxide ceramic, outperforming alumina in impact and sliding wear; at extreme temperatures, fully stabilized YSZ crucibles and setter plates operate in oxidizing atmospheres up to 2,000–2,100 °C while resisting molten superalloys, platinum-group metals, and lithium-rich battery oxides.
Supplied as crucibles, furnace tubes, calcination saggers, oxygen-ion solid-electrolyte discs, and precision ground wear rings.

Reference values reflect typical sintered, fused, or wrought grades. Exact batch test figures are confirmed on your written quotation and accompanying lot Certificate of Analysis.
Clarify whether your application is mechanical/wear (3 mol% Y2O3 fine-grain dense TZP) or ultra-high-temperature melting/calcining above 1,600 °C (8 mol% Y2O3 or CaO/MgO stabilized thermal-shock grade), along with geometry and heating rate.
Include target quantity, destination country/postal code for express air freight calculation, and any special cleanroom bagging or certification requests.
