Uses Of Glass Ceramics

The tools used on construction sites are often made with ceramics too.

Uses of glass ceramics.

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. 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. 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.

One particularly notable use of glass ceramics is in the processing of ceramic matrix composites. Bio ceramics are used as dental implants and synthetic bones. Glass ceramics are also stronger at high temperatures than glasses. Ceramic products are hard porous and brittle.

The properties and uses of some glasses and glass ceramics are given in the table below. We can take blue and green light diodes and use our glass ceramics as a filter to obtain a wide spectrum emission that will include the ir range explains anastasia babkina. 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.
