Typical Ceramics and Respective Applications

Some typical ceramics and respective applications are as follows:

Aluminium oxide / Alumina (Al2O3): it is one of the most commonly used ceramic materials. It is used in many applications such as to contain molten metal, where material is operated at very high temperatures under heavy loads, as an insulator in spark plugs, and in some unique applications such as dental and medical use. Chromium-doped alumina is used for making lasers.

Alumina

Aluminum nitride (AlN): because of its typical properties such as good electrical insulation but high thermal conductivity, it is used in many electronic applications such as in electrical circuits operating at a high frequency. It is also suitable for integrated circuits. Other electronic ceramics include – barium titanate (BaTiO3) and Cordierite (2MgO-2Al2O3-5SiO2).

Diamond (C): it is the hardest material known to be available in nature. It has many applications such as industrial abrasives, cutting tools, abrasion-resistant coatings, etc. it is, of course, also used in jewelry.

Lead zirconium titanate (PZT): it is the most widely used piezoelectric material, and is used as gas igniters, ultrasound imaging, in underwater detectors.

Silica (SiO2): is an essential ingredient in many engineering ceramics, and thus is the most widely used ceramic material. Silica-based materials are used in thermal insulation, abrasives, laboratory glassware, etc. it also found application in communications media as an integral part of optical fibers. Fine particles of silica are used in tires, paints, etc.

Silicon carbide (SiC): it is known as one of the best ceramic materials for very high-temperature applications. It is used as coatings on other materials for protection from extreme temperatures. It is also used as an abrasive material. It is used as reinforcement in many metallic and ceramic-based composites. It is a semiconductor and is often used in high-temperature electronics. Silicon nitride (Si3N4) has properties similar to those of SiC but is somewhat lower, and found applications in such automotive and gas turbine engines.

Titanium oxide (TiO2): it is mostly found as a pigment in paints. It also forms part of certain glass ceramics. It is used to make other ceramics like BaTiO3.

Titanium boride (TiB2): it exhibits great toughness properties and hence found applications in armor production. It is also a good conductor of both electricity and heat.

Uranium oxide (UO2): it is mainly used as nuclear reactor fuel. It has exceptional dimensional stability because its crystal structure can accommodate the products of the fission process.

Yttrium aluminum garnet (YAG, Y3Al5O12): it has a main application in lasers (Nd-YAG lasers).

Zirconia (ZrO2): it is also used in producing many other ceramic materials. It is also used in making oxygen gas sensors, as an additive in many electronic ceramics. Its single crystals are part of the jewelry.
