Magnesia Zirconia Ceramic ring

  • The surface roughness can reach Ra0.02um
  • High flexural strength and hardness
  • High density – up to 6.0 g/cm^3
  • Low thermal conductivity – aprox. 10% of Alumina
  • Other characteristics: high electrical insulation, strong corrosion resistance, high biocompatibility


Magnesia Zirconia 

Magnesium stabilized zirconia has the highest fracture toughness. It has excellent mechanical properties, including high strength, fracture toughness, wear resistance, good thermal shock resistance and low thermal conductivity. With high wear and corrosion characteristics, magnesium stabilized zirconia is used in valves, pumps and gaskets. Magnesium stabilized zirconia is also the preferred material for chemical processing and petrochemical industry.

While Y-PSZ is well suited for demanding mechanical applications, it may not be suitable for very high temperature applications because it is affected by particle boundary slip; this occurs when long exposure to heat causes the material to transition from a strong tetragonal phase to a weaker monocyte phase. Mg-PSZ has better temperature and moisture resistance because it is not affected by phase migration. The Mg-PASZ maintains its strength even in humid and high-temperature environments where the mechanical properties of Y-PSZ begin to deteriorate.


Machinability application: it can be processed by common metal processing tools and various equipment, and can achieve high machining accuracy;
Application of insulating property: macor ceramics is a kind of excellent high temperature electrical insulation material, its breakdown strength per millimeter can reach 40KV/A;
Application of heat shock resistance: macor ceramics can be used in the range of – 200 ℃ ~ + 800 ℃. Because mica crystal in glass ceramics has certain elasticity, it can prevent the extension of microcracks, so it has better thermal shock resistance;
Application of corrosion resistance: macor ceramics have excellent corrosion resistance ;
Won’t outgas in vacuum environment;
Toxicological safety.
