Product Description

Industry Ceramic Injection Molding ZrO2 Threaded Zirconia Ceramic Tube

Description of threaded zirconia ceramic tube :

Zirconia (ZrO2) is the most outstanding high-performance material among all oxide ceramics. Zirconia ceramic components made out of Zirconia generally consist of zirconia as basic material doped with some percentage of other stabilizers like Yttria (Y2O3) or Magnesia (MgO), in the filed, it called partially stabilized. Depending on doping material, it will obtain better properties than pure zirconia because of influencing the stabilizers' microstructure, such as wear resistance, flexural toughness and so on.

The "ceramic steel" titled Zirconia is doped with Yttria forming an ultra-fine ductile structure with sub-micron grain formation leading to enormous bending strengths. Magnesia doped qualities are less strong also showing a coarser microstructure.

We focus on producing a wide range of zirconia ceramic parts, including ceramic tube, ceramic ring, ceramic spacer, ceramic disc, ceramic plate with various different grades with respect to the accuracy, surface quality.

Benefits of zirconia ceramic bushing:

1. Excellent wear resistance, much higher 276 times than stainless steel

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

3. High hardness, over than 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

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.
