A ceramic is an inorganic, nonmetallic[a] sound 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., glasses). Varying crystallinity and electron utilization in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (thoroughly explored in ceramic engineering). With such a large range of possible options for the composition/structure of the ceramic (e.g. all of the elements practically, almost all types of bonding, and all levels of crystallinity), the breadth of the topic is vast, and identifiable characteristics (e.g. hardness, toughness, electric conductivity, etc.) are hard to designate for the merged 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, goblet transition heat range, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibre, while comprising ceramic materials, aren't regarded as area of the ceramic family.The indicated term "ceramic originates from the Greek phrase ????????? (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, "staff of ceramics", written in Linear B syllabic script.[5] The word "ceramic" can be utilized 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 made by humans were pottery objects, including 27,000-year-old figurines, made from clay, either alone or mixed with other materials like silica, solidified, sintered, in open fire. Ceramics were glazed and fired to produce soft later, colored surfaces, lessening porosity by using glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include home, commercial and building products, as well as an array of ceramic art.
