Product Description High Precision Low Friction Wear Resistance Zirconia Ceramic Valve SeatThe main features of the zirconia ceramic valve seat1.High density: over 6 g/cm3, which makes it the densest body of the ceramic products2.High hardness: over 9 on Mohs scale, diamond being 10, with a satin-smooth surface finish3.High toughness: over 1200 MPa, approx. 4 times in comparison with 95% alumina4. Excellent wear resistance, it's much better than aluminum oxide ceramics with longer life cycle5. Low thermal conductivity: less than 3 W/m.k at ambient temperature, so it's an ideal thermal material6. Good chemical and corrosion resistance, it's equivalent to above 99% aluminaThe specification of ceramic partsMaterial optionZirconia (ZrO2), Alumina(Al2O3), Silicon carbide(SiO2), Silicon nitride(Si3N4)Forming methodsDry pressed, Ceramic injection molding, Hot pressed, ISO pressedSpecificationOD can be from 1 to 50mm, length can be from 10mm to 800mmPrecision processingCNC machining, Precision grinding, Polishing, Lapping, ToleranceThe tolerance of OD and ID can be 0.001mm, the tolerance of length can be 0.001mmKey parametersRoughness to be 0.02mm, Parallelism to be 0.001mmSurface qualityFree of cracks, foreign contamination, mirror surface better than Ra0.1The description of the zirconia ceramic valve seatZirconia ceramic valve seat is a key part of the various pumps, valves in household appliances, electrical appliances, and industrial applications. It plays a decisive role in liquid, gas, oil sealing, and controlling performance. With zirconium oxide ceramic outstanding properties, such as wear-resistance, chemical resistance, low thermal conductivity, high thermal expansion coefficient similar as stainless steel, very low friction coefficient, zirconia ceramic seal rings have been creating a very positive impact on aging features, service life-span, productivity, dependability in industrial equipment, mechanical engineering, like the food and beverage industry, medical equipment, electrical devices and so on.Besides the ceramic seal ring, we also produce a variety of customized ceramic valve seat, ceramic ball valve, ceramic valve disc, ceramic piston and plunger for fluid, gas, oil-controlling / regulating system.The gallery of zirconia ceramic parts Datasheet of Technical ceramicsPropertyUnitsMaterial 99.5%alumina99%alumina95%aluminaZrO2(Y-TZP)ZrO2(TTZ)Densityg/cm3≥3.85≥3.80≥3.60≥5.95≥5.72Water absorption%00000HardnessHV1700170015001300900Flexural strengthMpa≥379≥338≥320≥1200≥1200Compressive strengthMpa≥2240≥2240≥2000≥19901750Fracture toughnessMpa m1/24-54-53-46.5-811Max. servicetemperatureoC1675160014501000 CTE1×10 -6 /oC6.5~8.06.2~8.05.0~8.08.0~9.510.2Thermal shockT(oC)≥250≥200≥220≥300350Thermal conductivity(25oC)W/m.k30292433Volume resistivityohm.cm 25oC>1 x 10 14>1 x 10 14>1 x 10 14>1 x 10 11>1 x 10 11300oC1 x 10 128 x 10 1110 12 -10 131 x 10 101 x 10 10500oC5 x 10 102 x 10 91 x 10 91 x 10 61 x 10 6Insulation strengthKV/mm1918181720Dielectric constant(1Mhz)(E)9.79.59.52928 Manufacturing flow chart of technical ceramic partsWe have in-housing comprehensive manufacturing types of equipment, including forming, sintering,CNC machining, precision grinding, laser cutting, and so on, it helps us to control the quality very well.Also, it greatly benefits cost control.FAQs (Frequently Asked Questions)Q1.
