Ceramics Metal Oxides

Zirconium dioxide zro 2 sometimes known as zirconia not to be confused with zircon is a white crystalline oxide of zirconium its most naturally occurring form with a monoclinic crystalline structure is the mineral baddeleyite a dopant stabilized cubic structured zirconia cubic zirconia is synthesized in various colours for use as a gemstone and a diamond simulant.

Ceramics metal oxides.

Transition metal oxide ceramics from ii to iv such as tio 2 zno nio fe 2 o 3 sno 2 and others exhibit semiconductor properties and are used mainly for the applications of gas sensors solar energy and in the electronics industry. The most frequently used metal oxide ceramics are alumina al 2 o 3 and zirconia zro 2. Nextel fibers are spun dried and then sintered at high temperatures.
