Ceramic
◦ 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
