Learn about zirconia ceramic parts
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, and can withstand attacks from molten metal, organic solvents, strong acids, and strong alkalis. So zirconia ceramic parts are always used in various severe service conditions.
Jinghui ceramics provide many selections of zirconia ceramic parts in different types of partial stabilizers, such as yttria (Y2O3) stabilizer, magnesia stabilizer, and cerium stabilizer, also support various customized ceramic parts, including ceramic tubes, ceramic rings, ceramic shafts and ceramic rods. With our in-house comprehensive manufacturing equipment, we are capable of achieving ultra-precision ceramic components. Whatever it's a prototyping case or high volume demand, we believe we could help your business grow.
The main characteristics of zirconia ceramic parts
2. Higher density than most technical ceramics, over than 6 g/cm3
3. High hardness, over 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 m1/2
8. Chemical inertness, aging resistance, and not rust forever
9. Resistance to molten metals due to an extraordinary melting point
