Ceramic type of ceramic product n Properties

Ceramic: ceramic are inorganic non-metallic materials. Metal oxides (Al2O3, FeO) are common example of ceramic, but other compounds such as carbides and nitrides are also included porcelain, glass bricks and refractory materials are some examples of traditional ceramics.

Traditional ceramic raw materials include clay minerals such as kaolinite.

Properties of ceramic:

• a)      Ceramic materials are brittle, hard strong in compression, weak in shearing and tension.
• b)      They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
• c)       Ceramics generally can withstand very high temperature, such as temperature range from 1000-1600 C [1800-3000F]
• d)      Ceramic process involves several steps of the glass making and its mechanical properties are similar to ceramic materials.
• e)      Good chemical and corrosion resistance
• f)       High electrical resistivity ( although some ceramic are superconductors)

Types of ceramic Products: For convenience ceramic products are usually divided into four sectors these are shown below with some examples:

1.       Structural: Including bricks, Pipes, floor and roof tiles
2.        Refractories: such as kiln linings, gas fire radiants, steel and glass making crucibles.
3.     White wares: including tableware cookware, wall tiles pottery products and sanitary ware.
4.      Technical: is also known as engineering, advanced, special and in japan, fine ceramics such  items include tiles used in the space shuttle program, gas burner nozzles, ballistic protection, nuclear fuel uranium oxide pellets, oxide pellets, biomedical implants, coatings of jet engine turbine blades, ceramic disk brake, missile nose cones, bearing (mechanical) frequently the raw materials do not include clays.
