       ◦ chemical industry, machinery, electronics, aerospace, dental and

          biomedical engineering.


       ◦ Zirconia is an oxide ceramic material with special crystal structure
          transition characteristics. It adopts a monoclinic crystal structure at room

          temperature and transitions to tetragonal and cubic at higher

          temperatures , which possesses excellent properties such as the high
          flexural strength, high fracture toughness, excellent ionic conductivity,

          thermal and chemical stability, good biocompatibility and corrosion

          resistance


       ◦ Alumina powder Alpha-alumina is a ceramic with excellent chemical
          stability, mechanical property, high melting point, and insulating

          property
