How do you describe ceramics?
A ceramic is an inorganic non-metallic solid made up of either metal or non-metal compounds that have been shaped and then hardened by heating to high temperatures. In general, they are hard, corrosion-resistant and brittle.
How are ceramics classified?
Ceramics are classified as inorganic and nonmetallic materials that are essential to our daily lifestyle.
Why ceramics are useful?
Ceramic based objects are useful because it is cheap to buy, it can be made into many things and although it is fragile and brittle it is a yet a strong product. Some popular ceramic products are kitchenware like plates, mugs, knives and even ceramic cook tops because ceramics is heat resistant and is a thermoset.
Why is ceramic important?
IMPORTANT PROPERTIES Ceramics can withstand high temperatures, are good thermal insulators, and do not expand greatly when heated. This makes them excellent thermal barriers, for applications that range from lining industrial furnaces to covering the space shuttle to protect it from high reentry temperatures.
How is ceramics used in construction?
Ceramic products for the construction sector include cements and cement-based materials, interior and exterior tiles, sanitary ware, non-refractory bricks, and other more complex shapes such as drainage, sewer, and chimney pipes and linings. Cements are used to make mortar and concrete.

What is ceramics and its properties?
Explanation: Ceramics are nonmetallic, inorganic solids which are used at high temperatures and therefore have a high melting point. They are good thermal and electrical insulators and possess good resistance to oxidation and corrosion.
