Product Description

Industrial Wear Resistant Precision Zirconia Ceramic Bar Rod for Medicals

The specification of ceramic bars 

1. Material availability Zirconia, alumina, silicon carbide, silicon carbide
2. Shaping method: ISO pressing, Dry pressed, Ceramic injection molding
3. Specification: available side-length from 1mm to 50mm, the thickness to be 30mm
4. Tolerance: side-length greater than 0.01mm after grinding, overall length to be 0.10mm 
5. Surface finish: the working surface to be diamond polished up to Ra0.1, or better

Main features of the zirconia ceramic rod and bar

1. Can withstand higher temperatures up to 2400°

2. High hardness, over than 1300 MPa for Vicker

3. Exceptional fracture toughness reaches up to 8 Mpa m1/2

4. Low thermal conductivity, less than 3 W/m.k at room temperature

5. Higher density than most of technical ceramics, over than 6 g/cm3

6. Chemical inertness, not interact with almost all strong acid and alkali

7. Resistance to molten metals due to an extraordinary melting point 
8. Good Wear resistance, over 276 times than stainless steel

Description of zirconia ceramic bar:

Our facility manufactures a wide range of zirconia ceramic rod shafts by cold ISO pressing, dry pressing or ceramic injection molding. All these zirconia ceramic rods are with a dense ceramic body. In order to reduce the friction further, the cylindrical surface will be polished to be a mirror effect.

We have been dealing with various standard and customized zirconia ceramic rods, including the dimensions, different grades of zirconia, different shapes, different surface treatments and so on.


Application of zirconia ceramic rods and bars:

Zirconia ceramic rods and bars are widely used in the fields of industry, chemical industry, biology, semiconductor, precision machinery, and high technology because of their excellent mechanical, electrical, thermal, mechanical, and biochemical properties.
