high alumina ceramic tube,
porous ceramic tubes
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.

We have in-housing comprehensive manufacturing types of equipment, including forming, sintering, CNC machining,
precision grinding, laser cutting and so on, it helps us to control the quality very well, also it greatly benefits cost control.
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.
