Glass ceramics are also stronger at high temperatures than glasses.
Uses of glass ceramics.
The tools used on construction sites are often made with ceramics too.
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.
As a result they are used to make pottery bricks tiles cements and glass.
Ceramic products are hard porous and brittle.
Bio ceramics are used as dental implants and synthetic bones.
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.
Ceramics are also used at many places in gas turbine engines.
The properties and uses of some glasses and glass ceramics are given in the table below.
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.
If aerospace is an extraordinary use for extraordinary ceramics construction is one of the best known uses for ordinary everyday ceramics.
