Alumina ceramic

Alumina ceramic is very popular use in the medical industry such as the manufacture of artificial limbs and joints. Alumina can be used for hip replacement. Another example alumina is also used for ballistic armor in the military but it is also used for high resistance to shock on the vehicle.

Ceramic components are also the most widely use such material. The material is also relatively cheap and the end products are also reasonably priced so that many used a variety of applications.
Properties with low density and is also resistant to high temperatures. This material is often used as a bearing and crucibles in the furnace.
Alumina has a good thermal conduction properties as well as dielectric properties.
For the most widely used in automotive spark plugs.

Because the resistance is then the alumina ceramic has a myriad applications ranging from a variety of purposes in industry, aerospace, military and oil drilling.
Utilities on the temperature measurement is also used 99% alumina thermocouple attached to the metal and is connected with standard cable for instrumentation.

Clearly the alumina ceramic material widely used for high temperature applications and are also very suitable resistance to aggressive chemicals and wear.
