A ceramic can be an inorganic, nonmetallic[a] sturdy material comprising metallic, 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., spectacles). Differing crystallinity and electron use in the ionic and covalent bonds cause most ceramic materials to be good thermal and electronic insulators (extensively investigated in ceramic anatomist). With such a huge range of possible options for the structure/structure of the ceramic (e.g. nearly all of the elements, all sorts of bonding practically, and all levels of crystallinity), the breadth of the topic is great, and identifiable characteristics (e.g. hardness, toughness, electric conductivity, etc.) are hard to designate for the mixed 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, a glass transition temps, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibers, while comprising ceramic materials, aren't considered to be area of the ceramic family.The expressed 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 mention of the main "ceram-" is the Mycenaean Greek ke-ra-me-we, "personnel of ceramics", written in Linear B syllabic script.[5] The word "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 earliest ceramics made by humans were pottery items, including 27,000-year-old figurines, made from clay, either alone or mixed with other materials like silica, solidified, sintered, in flame. Later ceramics were glazed and terminated to generate smooth, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include domestic, professional and building products, as well as a variety of ceramic art. Within the 20th century, new ceramic materials were developed for use in advanced ceramic anatomist, such such as semiconductors.Ceramic artifacts provide an important role in archaeology for understanding the culture, action and technology of peoples of days gone by. These are among the most typical artifacts to be found at an archaeological site, generally by means of small fragments of broken pottery called sherds. Processing of accumulated sherds can be steady with two main types of analysis: complex and traditional.Traditional analysis will involve sorting ceramic artifacts, sherds and larger fragments into specific types predicated on style, composition, manufacturing and morphology. By creating these typologies it is possible to distinguish between different cultural styles, the goal of the ceramic and technological state of the individuals among other conclusions. In addition, by looking at stylistic changes of ceramics as time passes can you really separate (seriate) the ceramics into distinct diagnostic groups (assemblages).
