A ceramic is an inorganic, nonmetallic[a] sound material comprising steel, nonmetal or metalloid atoms generally held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and frequently completely amorphous (e.g., glasses). Varying crystallinity and electron usage in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical power insulators (extensively researched in ceramic anatomist). With such a sizable range of possible options for the composition/structure of an ceramic (e.g. every one of the elements practically, all sorts of bonding practically, and all degrees of crystallinity), the breadth of the subject is huge, and identifiable qualities (e.g. hardness, toughness, electric conductivity, etc.) are hard to identify for the group all together. General properties such as high melting temperature, high hardness, poor conductivity, high moduli of elasticity, chemical resistance and low ductility will be the norm,[1] with known exceptions to each one of these rules (e.g. piezoelectric ceramics, cup transition heat range, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fibre, while formulated with ceramic materials, are not regarded as part of the ceramic family.The term "ceramic originates from the Greek word ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The initial known reference to the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "personnel of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to spell it out a material, product or process, or it might be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The initial ceramics created by humans were pottery items, including 27,000-year-old figurines, made from clay, either alone or mixed with other materials like silica, solidified, sintered, in fire.
