Ceramic. About ceramic.Ceramic. About ceramic.
 A ceramic is an inorganic, non-metallic solid prepared by the action of heat and subsequent cooling. Ceramic materials may well have a crystalline or partly crystalline structure, or may well be amorphous (e.g., a glass). For the reason that most frequent ceramics are crystalline, the definition of ceramic is typically restricted to inorganic crystalline materials, as opposed to the non-crystalline glasses.The earliest ceramics had been pottery objects created from clay, either by itself or mixed with other supplies, hardened in fire. Later ceramics were glazed and fired to produce a colored, smooth surface. Ceramics now incorporate domestic, industrial and building goods and art objects. Inside the 20th century, new ceramic supplies were developed for use in advanced ceramic engineering; as an example, in semiconductors. The word ceramic comes from the Greek word (keramikos), "of pottery" or "for pottery", from (keramos), "potter's clay, tile, pottery". The earliest mention on the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "workers of ceramics", written in Linear b syllabic script. Ceramic could be used as an adjective describing a material, item or procedure; or as a singular noun, or, far more generally, as a plural noun, ceramics.
