Also used as a reractory material (i.e resistant to very high temperatures), the alumina has a high hardness, excellent electrical properties and a high corrosion's resistance.
Because of its hardness, zirconia has a good wear resistance and the ability to give differents tints (black, white, pink, etc.). It's used as a material for luxury's production in jewelery, costume jewelry and watchmaking. Zirconia is also used in the medical field for dental prostheses or artificial femoral heads of hip joints's production.
Quartz has a very high chemical purity. Its low expansion's coefficient provides excellent thermal shock resistance. Moreover, its piezoelectric properties allow to obtain very precise oscillating frequencies, which make it a must used component in digital electronics as well as analog electronics.
Silicon Carbide (SIC)
Silicon carbide is an hard body and is thermally stable. It offers low friction and corrosion resistance by hard bases and hard acids. Carbide has found its applications in the chemical industry and in the construction of precise furnaces, such as pumps's component.
White sapphire is mainly used in the field of watchmaking. It is found in the manufacture of premium ice shows.
Glass-ceramic is a glass whose properties tend to join those of ceramic while remaining transparent. Its most notable feature is its absence of high-temperature dilatation. Its means that on glass-ceramic, local heating produces no expansion.
The glass-ceramic remains as strong as if it had remained consistently cold.
Zerodur is a glass ceramic whose dilatation coefficient is almost zero and whose homogeneity of this coefficient in materials is excellent.
Zerodur is used for mirror substrates requiring very high thermal stability.
