If aerospace is an extraordinary use for extraordinary ceramics construction is one of the best known uses for ordinary everyday ceramics.
Uses of glass ceramics.
Given below are some other important uses of ceramics.
Ceramic products are hard porous and brittle.
Even in our modern age of plentiful plastics brick glass cement concrete porcelain and tiles of all kinds are still the raw materials from which most buildings are made.
As a result they are used to make pottery bricks tiles cements and glass.
Glass ceramics are also stronger at high temperatures than glasses.
For many ceramic matrix composites typical sintering temperatures and times cannot be used as the degradation and corrosion of the constituent fibres becomes more of an issue as temperature and sintering time increase.
The tools used on construction sites are often made with ceramics too.
One particularly notable use of glass ceramics is in the processing of ceramic matrix composites.
Thus the glass ceramic mgo al 2 o 3 sio 2 is used to make electrical insulators that have to operate at high temperatures such as spark plug insulators.
Ceramics are also used at many places in gas turbine engines.
As well as providing a bond to metals in which the glass ceramic provides a bulk component closely matched in thermal expansion 1 6 glass ceramics are very useful as media for joining together ceramic to ceramic and ceramic to metal 9 in cases where the major components are matched in expansion or where mismatch occurs.
