Material introduction:

Zirconia ceramic linear guide:

Zirconia has the highest strength and toughness at room temperature of all the advanced ceramic materials. The fine grain size allows for extremely smooth surfaces and sharp edges.

Applications include scissors, knifes, slitters, pump shafts, metal-forming tools, fixtures, tweezers, wire drawing rings, bearing sleeves and valves.

Product Description

Zirconia Ceramics (ZrO2) especially Yttria Stabilized Zirconia Ceramics (Y-PSZ) is a commonly used technical ceramic material. It has relatively high fracture strength among all ceramic materials, with the addition of high hardness and low friction coefficient, it is usually used for structural ceramic components. Its thermal expansion coefficient is similar to steel, so it can be jointed to steel parts. Besides, it has excellent corrosion resistance and low thermal conductivity.

Typical applications include ceramic valve components, ceramic grinding&milling media, ceramic knife blades for various using, mechanical liners or bearing balls etc.

Zirconium oxide occurs as monoclinic, tetragonal and cubic crystal
forms. Densely sintered parts can be manufactured as cubic
and/or tetragonal crystal forms. In order to stabilise these crystal
structures, stabilisers such as magnesium oxide (MgO), calcium
oxide (CaO) or yttrium oxide (Y2O3) need to be added to the ZrO2.
Other stabilisers sometimes used are cerium oxide (CeO2),
scandium oxide (Sc2O3) or ytterbium oxide (Yb2O3).

Unlike other ceramic materials, zirconia is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.

 high fracture toughness

 thermal expansion similar to cast iron

 extremely high bending strength and tensile strength

 high resistance to wear and to corrosion

 low thermal conductivity
