Magnesium Stabilized Zirconia Ceramic Tubes High Precision
High-Precision Magnesium Stabilized Zirconia Ceramic Tubes
High temperature magnesium stabilized zirconia ceramic tubes
Description:
Magnesium oxide stabilized zirconia ceramics, zirconia toughened ceramics prepared by magnesium oxide as stabilizer. Cubic zirconia and metastable tetragonal zirconia ceramics can be prepared according to the different content of magnesium oxide stabilizer and preparation process. By controlling the growth of tetragonal crystal nucleus, magnesium oxide partially stabilized zirconia ceramics with the best bending strength and fracture toughness can be obtained. Its application is roughly the same as yttrium oxide stabilized zirconia ceramics. And more because of its unique thermal shock resistance.
Principal characteristic of High-precision magnesium stabilized zirconia ceramic tubes:
1. Excellent fracture toughness.
2. good wear resistance.
3. corrosion resistance.
4. good thermal shock.
Application of High-precision magnesium stabilized zirconia ceramic tubes:
Because of its resistance to wear and corrosion, it is mainly used in valves, pumps and gaskets, and is also used in chemical processing and petrochemical industries.
