Product Description

Industry MgO Stabilized Zirconia ZrO2 / Zirconium Oxide Ceramic Rods

Prime features of zirconia ceramic rods:

1. Higher density than most of technical ceramics, over than 6 g/cm3
2. High hardness, over than 1300 MPa for Vicker

3. Can withstand higher temperatures up to 2400°

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

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

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

Specification of ceramic rods: 

1. Material options: YSZ zirconia, TTZ zirconia, 95~99.5% alumina, Silicon carbide (SiC)
2. Forming method: Extruding, Dry pressed, Ceramic injection molding and ISO pressing
3. Specification: Available outer from 1mm to 50mm, available length from 3mm to 2000mm
4. Tolerance A: Diameter below 12.5mm, tolerance ± 3% or ± 0.076 mm, whichever is greater. Straightness: camber / length < 0.003
5. Tolerance B: Diameter above 12.5mm, tolerance ± 5% or ± 0.76 mm, whichever is greater. Straightness: ≤ 0.006″/1.000″ cumulative
6. Surface finish: the working surface to be diamond polished up to Ra0.1, or better

Description of zirconia ceramic rods:

Zirconia (ZrO2) is an exceptional heat resistant material. They exhibit excellent chemical inertness and chemistry resistance at high temperatures up to 2200℃, well above the melting point of alumina. Zirconia is stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. It's always an ideal option for high pressure, easily breakage application.

Zirconia ceramic rods/bars have the advantages of super hardness, high wear-resisting, high-temperature tolerance, good corrosion resistance, very low friction coefficient, high strength, high mechanical strength, good chemical stability, polishing surface and so on. All these ceramic components can offer high dimensional accuracy, mirror surface, and stringent straightness via fine grinding and diamond polishing.

We have been supplying with many selections of regular diameters with custom lengths, also we are capable of producing various of special shapes, customized diameters in specific materials.


Application of zirconia ceramic rods:

Zirconia ceramic rod/bar is used in the shaft, plunger, automobile Industrial,  sealing structure, oil drilling equipment, Insulation parts in electrical equipment, electronic engineering, industrial machinery, and ceramic hair clipper spare parts, with high density, bending strength and breaking tenacity.

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other,

to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
