Product Description Refractory Industrial Wear Resistance Yttria Stabilized Zro2 White Zirconia TubesThe main characteristics of zirconia ceramic tubes1. Excellent wear resistance, much higher 276 times than stainless steel2. Higher density than most technical ceramics, over than 6 g/cm33. High hardness, over 1300 MPa for Vicker4. Can withstand higher temperatures up to 2400°5. Low thermal conductivity, less than 3 W/m.k at room temperature6. Similar coefficient of thermal expansion as stainless steel7. Exceptional fracture toughness reaches up to 8 Mpa m1/28. Chemical inertness, aging resistance, and not rust forever 9. Resistance to molten metals due to an extraordinary melting pointThe specification of ceramic tubesMaterial optionZirconia (ZrO2), Alumina(Al2O3), Silicon carbide(SiO2), Silicon nitride(Si3N4)Forming methodsDry pressed, Ceramic injection molding, Hot pressed, ISO pressedAvailable typesFlanged tubes, slotted tubes, one-end closed tubes, square tubesSpecificationOD can be from 1 to 50mm, length can be from 10mm to 500mmPrecision processingCNC machining, Precision grinding, Polishing, Lapping, ToleranceThe tolerance of OD and ID can be 0.001mm, the tolerance of length can be 0.001mmSurface qualityFree of cracks, foreign contamination, mirror surface better than Ra0.1Key parametersRoughness to be 0.02mm, Parallelism to be 0.001mmThe description of zirconia ceramic tubesZirconium oxide, also called Zirconia, is an extremely tough technical ceramic with a hardness of >9 Mohs. Zirconia has the highest strength and fracture toughness at room temperature among all the advanced ceramic materials, In addition to withstanding attacks from molten metal, organic solvents, strong acids, and strong alkalis. So zirconia ceramic parts always used in various severe service conditions.Jinghui ceramics provide many selections of zirconia ceramic tubes in different types of partial stabilizers, such as yttria (Y2O3) stabilized tube, magnesia (MgO) stabilized tube, Cerium stabilized tube, also we support various customized ceramic tubes with flanged, slotted, multiple holes, half tubes. Whatever, it's a prototyping case or high volume demand, we could help your business.The gallery of zirconia ceramic tubes Datasheet of Technical ceramicsPropertyUnitsMaterial99.5%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.
