A ceramic is an inorganic, nonmetallic[a] sturdy material comprising metal, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, 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 electro-mechanical insulators (extensively investigated in ceramic anatomist). With such a sizable range of possible options for the composition/structure of your ceramic (e.g. almost all of the elements, all types of bonding nearly, and all degrees of crystallinity), the breadth of the topic is huge, and identifiable qualities (e.g. hardness, toughness, electro-mechanical conductivity, etc.) are hard to specify 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, glass transition temps, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fiber, while including ceramic materials, aren't regarded as area of the ceramic family.The portrayed word "ceramic originates from the Greek term ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The earliest 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" can be utilized as an adjective to spell it out a material, product or process, or it might be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The earliest ceramics created by humans were pottery items, including 27,000-year-old figurines, created from clay, either alone or blended with other materials like silica, hardened, sintered, in flames.
