high alumina ceramic tube,
porous ceramic tubes
Zirconia (ZrO2) is an extraordinary refractory technical ceramic material. It possesses excellent chemical inertness and corrosion resistance at 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. So it's easier to proceed with high precision processing. In addition to their refractoriness, they offer low thermal conductivity and are electrical conductors above 800 ℃. They also possess the unique ability to allow oxygen ions to move freely through the crystal structure above 600 ℃.
Zirconia ceramic bushings have the advantages of super hardness, high wear-resisting, good corrosion resistance, high-temperature tolerance, high strength, high mechanical strength, good chemical stability, polishing surface and so on.
1. High precision dimensions, it can fit with other parts perfectly
2. Higher density than most of technical ceramics, over than 6 g/cm3
3. Excellent wear resistance, much higher 276 times than stainless steel
4. High hardness, over than 1300 MPa for Vicker
5. Can withstand higher temperatures up to 2400°
6. Low thermal conductivity, less than 3 W/m.k at room temperature
7. Similar coefficient of thermal expansion as stainless steel
8. Exceptional fracture toughness reaches up to 8 Mpa m1/2
9. Corrosion resistance, withstand strong acid and alkali in high-temperature conditions
10. Resistance to molten metals due to an extraordinary melting point

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.
