Product Description

The description of 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,
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 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, ceramic rod. 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.
