A ceramic can be an inorganic, nonmetallic[a] stable material comprising metallic, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., spectacles). Varying crystallinity and electron usage in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical power insulators (thoroughly investigated in ceramic engineering). With such a big range of possible options for the composition/structure of your ceramic (e.g. all of the elements practically, almost all types of bonding, and all degrees of crystallinity), the breadth of the subject is huge, and identifiable capabilities (e.g. hardness, toughness, electro-mechanical conductivity, etc.) are hard to designate for the blended group all together. 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, glass transition temps, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibers, while made up of ceramic materials, aren't considered to be area of the ceramic family.The term "ceramic comes from the Greek phrase ????????? (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, "staff of ceramics", written in Linear B syllabic script.[5] The term "ceramic" can be utilized as an adjective to describe a material, product or process, or it might be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The initial ceramics made by humans were pottery items, including 27,000-year-old figurines, created from clay, either alone or blended with other materials like silica, solidified, sintered, in flame. Later ceramics were glazed and terminated to create simple, colored surfaces, lowering porosity by using glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include domestic, professional and building products, as well as a wide range of ceramic art. Within the 20th hundred years, new ceramic materials were developed for use in advanced ceramic engineering, such just as semiconductors.Ceramic artifacts produce an important role in archaeology for understanding the culture, technology and action of peoples of the past. They are among the most common artifacts found at an archaeological site, generally by means of small fragments of broken pottery called sherds. Handling of gathered sherds can be regular with two main types of examination: technical 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 you'll be able to distinguish between different cultural styles, the goal of the ceramic and technological state of the people among other conclusions. In addition, by looking at stylistic changes of ceramics as time passes is it possible to separate (seriate) the ceramics into distinct diagnostic groups (assemblages).
