Product Description Zirconia ceramics have high fracture toughness, excellent wear resistance, strong bending resistance, and good thermal insulation. It has almost the same thermal expansion capacity as steel. So we can use it in structural ceramics. The high-temperature performance of zirconia ceramic is excellent, so it can be used to produce Heating elements and refractory materials. Zirconia ceramics have good electrical sensitivity, so that they can be used to make oxygen sensors and solid oxides. Besides, zirconia ceramic products include valve trim, precision balls, nozzles, tool and pump liners, plungers, blades, and so on. Zirconia ceramics have many advantages and characteristics, with many applications for it. Zirconia ceramics have a dimensional hardness of 11.5 GPa, a density of 6.0g/cm3, and a compressive strength of 2100 MPa. Zirconia ceramics are widely used as ductile ceramics with fracture toughness up to 8.0 mpAM1/2.Applications: machinery, optical fiber, cutting tools, food, chemical, aerospaceCeramic material composition:- - 95%--99.99% Alumina (Al2O3)- - Silicon Carbide · Silicon Nitride- - TTZ: Magnesia partially stabilized Zirconia (ZrO2)- - YTZP: Yttria partially stabilized Zirconia (ZrO2)- - ZDY: Yttria fully stabilized Zirconia (ZrO2)Properties of Zirconium Oxide (ZrO2)* High thermal expansion (α=11 x 10-6/K, similar to some types of steel)* Excellent thermal insulation/low thermal conductivity (2.5 to 3 W/mK)* Very high resistance to crack propagation, high fracture toughness (6.5 to 8 MPam1/2)* Ability to conduct oxygen ions (used for the measurement of oxygen partial pressures in lambda probes) (3Y-TZP)Zirconia Ceramic PropertiesItemUnitTypical ValuesPhysical PropertiesColour WhiteDensityg/cm3>6Zirconia Content%94.80%Gas Permeability 0Water Absorption%0%Crystal Sizeμm0.5Mechanical PropertiesRockwell Hardness(45N)R45N90Vickers Strength(Load 500g)Gpa(Kg/mm2)11.5(1175)Flexural Strength(20)Mpa1200Compressive Strength(20)Mpa2100Modulus of Elasticity(20)Gpa>200Poisson's Ratio(20) 0.22-0.23Fracture Toughness(20)Mpam?8Thermal PropertiesThermal Conductivity(20-400)W/ (m.K)2.5Thermal Expansion Coefficient10-6 /10Thermal Resistance△T250
