A ceramic can be an inorganic, nonmetallic[a] solid material comprising metal, nonmetal or metalloid atoms generally held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and frequently completely amorphous (e.g., eyeglasses). Varying crystallinity and electron intake in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (thoroughly investigated in ceramic executive). With such a big selection of possible options for the composition/structure of the ceramic (e.g. nearly all of the elements, almost all types of bonding, and all levels of crystallinity), the breadth of the topic is great, and identifiable attributes (e.g. hardness, toughness, electric conductivity, etc.) are hard to designate for the blended 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 temps, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fiber, while made up of ceramic materials, are not considered to be part of the ceramic family.The portrayed word "ceramic comes from the Greek term ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The initial known mention of the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "individuals of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to spell it out a material, process or product, or it might be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The earliest ceramics made by humans were pottery items, including 27,000-year-old figurines, made from clay, either by itself or mixed with other materials like silica, hardened, sintered, in fireplace. Ceramics were glazed and terminated to make clean later, colored surfaces, lessening porosity by using glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include domestic, commercial and building products, as well as an array of ceramic art.
