Product Description

High Precision YSZ ZrO2 Yttria Stabilized White Zirconia Ceramic Tube

The main characteristics of zirconia ceramic tubes
1. Excellent wear resistance, much higher 276 times than stainless steel
2. Higher density than most of technical ceramics, over than 6 g/cm3
3. High hardness, over than 1300 MPa for Vicker
4. Can withstand higher temperatures up to 2400°
5. Low thermal conductivity, less than 3 W/m.k at room temperature
6. Similar coefficient of thermal expansion as stainless steel
7. Exceptional fracture toughness reaches up to 8 Mpa m^1/2
8. Chemical inertness, aging resistance and not rust forever 
9. Resistance to molten metals due to an extraordinary melting point

The description of zirconia ceramic tubes
Zirconium 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.
