A ceramic is an inorganic, nonmetallic[a] sound material comprising steel, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and frequently completely amorphous (e.g., glasses). Differing crystallinity and electron intake in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical power insulators (thoroughly explored in ceramic engineering). With such a large range of possible options for the structure/structure of an ceramic (e.g. all of the elements nearly, all types of bonding nearly, and all levels of crystallinity), the breadth of the subject is huge, and identifiable features (e.g. hardness, toughness, electrical power conductivity, etc.) are hard to identify for the merged 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, goblet transition heat, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass dietary fiber, while containing ceramic materials, are not considered to be area of the ceramic family.The word "ceramic comes 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 term "ceramic" may be used as an adjective to spell it out a material, product or process, or it could be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The earliest ceramics made by humans were pottery items, including 27,000-year-old figurines, made from clay, either alone or blended with other materials like silica, solidified, sintered, in open fire.
