A ceramic is an inorganic, nonmetallic[a] solid material comprising metal, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and often completely amorphous (e.g., glasses). Differing crystallinity and electron utilization in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric powered insulators (thoroughly explored in ceramic engineering). With such a large selection of possible options for the structure/structure of a ceramic (e.g. all of the elements practically, all types of bonding practically, and all degrees of crystallinity), the breadth of the topic is huge, and identifiable capabilities (e.g. hardness, toughness, electro-mechanical conductivity, etc.) are hard to identify 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, goblet transition temperatures, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass dietary fiber, while containing ceramic materials, are not considered to be area of the ceramic family.The term "ceramic originates from the Greek word ????????? (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, "employees of ceramics", written in Linear B syllabic script.[5] The term "ceramic" may be used as an adjective to describe a material, process or product, or it might be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The initial ceramics created by humans were pottery objects, including 27,000-year-old figurines, made from clay, either alone or mixed with other materials like silica, hardened, sintered, in fireplace. Later ceramics were glazed and terminated to produce even, colored surfaces, lowering porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include home, professional and building products, as well as an array of ceramic art. Within the 20th hundred years, new ceramic materials were developed for use in advanced ceramic executive, such such as semiconductors.Ceramic artifacts provide an important role in archaeology for understanding the culture, technology and patterns of individuals of days gone by.
