A ceramic can be an inorganic, nonmetallic[a] sound material comprising metallic, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., glasses). Differing crystallinity and electron use in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric powered insulators (extensively researched in ceramic anatomist). With such a big selection of possible options for the composition/structure of your ceramic (e.g. almost all of the elements, all sorts of bonding almost, and all levels of crystallinity), the breadth of the subject is huge, and identifiable qualities (e.g. hardness, toughness, electro-mechanical conductivity, etc.) are hard to specify for the combined 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 of these rules (e.g. piezoelectric ceramics, wine glass transition temperature, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibers, while including ceramic materials, aren't considered to be area of the ceramic family.The indicated expression "ceramic originates from the Greek expression ????????? (keramikos), "of pottery" or "for pottery",[3] from ???????
