A ceramic can be an inorganic, nonmetallic[a] stable material comprising steel, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and frequently completely amorphous (e.g., eyeglasses). Differing crystallinity and electron usage in the ionic and covalent bonds cause most ceramic materials to be good thermal and electro-mechanical insulators (extensively explored in ceramic executive). With such a big range of possible options for the structure/structure of any ceramic (e.g. every one of the elements nearly, almost all types of bonding, and all levels of crystallinity), the breadth of the topic is huge, and identifiable qualities (e.g. hardness, toughness, electric powered conductivity, etc.) are hard to specify 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 are the norm,[1] with known exceptions to each one of these rules (e.g. piezoelectric ceramics, wine glass transition heat, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fiber content, while comprising ceramic materials, aren't considered to be area of the ceramic family.The portrayed word "ceramic comes from the Greek expression ????????? (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, "workers 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 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 blended with other materials like silica, solidified, sintered, in flame. Ceramics were glazed and fired to build smooth later, colored surfaces, lessening porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include local, commercial and building products, as well as an array of ceramic art.
