A ceramic is an inorganic, nonmetallic[a] solid material comprising material, nonmetal or metalloid atoms primarily 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 intake in the ionic and covalent bonds cause most ceramic materials to be good thermal and electro-mechanical insulators (extensively researched in ceramic anatomist). With such a sizable selection of possible options for the structure/structure of an ceramic (e.g. almost all of the elements, nearly all types of bonding, and all degrees of crystallinity), the breadth of the topic is vast, and identifiable attributes (e.g. hardness, toughness, electronic conductivity, etc.) are hard to specify for the 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 of these rules (e.g. piezoelectric ceramics, wine glass transition temperature, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon dietary fiber, while containing ceramic materials, aren't regarded as area of the ceramic family.The portrayed term "ceramic comes from the Greek term ????????? (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, "individuals of ceramics", written in Linear B syllabic script.[5] The term "ceramic" can be utilized as an adjective to spell it out a material, process or product, or it could be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The initial ceramics created by humans were pottery things, including 27,000-year-old figurines, created from clay, either by itself or mixed with other materials like silica, solidified, sintered, in flame. Ceramics were glazed and terminated to generate simple later, colored surfaces, lessening porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include local, industrial and building products, as well as a wide range of ceramic art. Inside the 20th hundred years, new ceramic materials were developed for use in advanced ceramic executive, such as with semiconductors.Ceramic artifacts have an important role in archaeology for understanding the culture, habit and technology of peoples of days gone by. They may be among the most common artifacts to be found at an archaeological site, generally by means of small fragments of broken pottery called sherds.
