A ceramic is an inorganic, nonmetallic[a] solid material comprising metallic, nonmetal or metalloid atoms mostly held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., spectacles). Differing crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electro-mechanical insulators (extensively researched in ceramic engineering). With such a huge range of possible options for the structure/structure of a ceramic (e.g. all of the elements nearly, all sorts of bonding practically, 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 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, goblet transition temperatures, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass dietary fiber, while made up of ceramic materials, aren't considered to be area of the ceramic family.The word "ceramic comes from the Greek expression ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The initial 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 word "ceramic" can be utilized as an adjective to describe a material, product or process, or it may be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The initial ceramics created by humans were pottery items, including 27,000-year-old figurines, created from clay, either alone or mixed with other materials like silica, hardened, sintered, in hearth. Ceramics were glazed and fired to produce easy later, colored surfaces, lessening porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include home, industrial and building products, as well as a variety of ceramic art. Inside the 20th hundred years, new ceramic materials were developed for use in advanced ceramic executive, such as in semiconductors.Ceramic artifacts have an important role in archaeology for understanding the culture, technology and patterns of individuals of the past. They are among the most common artifacts to be found at an archaeological site, generally by means of small fragments of broken pottery called sherds.
