A ceramic is an inorganic, nonmetallic[a] sound material comprising metallic, nonmetal or metalloid atoms mostly 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 electric powered insulators (thoroughly researched in ceramic anatomist). With such a large range of possible options for the structure/structure of your ceramic (e.g. all the elements practically, almost all types of bonding, and all degrees of crystallinity), the breadth of the topic is vast, and identifiable features (e.g. hardness, toughness, electric conductivity, etc.) are hard to designate for the combined group as a whole. 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 temp, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fibers, while filled with ceramic materials, are not regarded as part of the ceramic family.The portrayed word "ceramic originates from the Greek term ????????? (keramikos), "of pottery" or "for pottery",[3] from ???????
