A ceramic can be an inorganic, nonmetallic[a] sturdy material comprising metal, 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., eyeglasses). Differing crystallinity and electron utilization in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric powered insulators (thoroughly investigated in ceramic executive). With such a large range of possible options for the composition/structure of any ceramic (e.g. nearly all of the elements, all sorts of bonding almost, and all levels of crystallinity), the breadth of the topic is vast, and identifiable traits (e.g. hardness, toughness, electrical power 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 will be 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 comprising ceramic materials, are not considered to be part of the ceramic family.The indicated term "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 term "ceramic" may be used as an adjective to describe a material, product or process, or it can be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The initial ceramics made by humans were pottery things, including 27,000-year-old figurines, made from clay, either by itself or mixed with other materials like silica, solidified, sintered, in open fire. Ceramics were glazed and terminated to build soft later, colored surfaces, lessening porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include home, commercial and building products, as well as a variety of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic executive, such just as semiconductors.Ceramic artifacts offer an important role in archaeology for understanding the culture, technology and habit of peoples of the past. They may be among the most typical artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Processing of accumulated sherds can be constant with two main types of examination: specialized and traditional.Traditional analysis consists of 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 scientific talk about of the public people among other conclusions. Furthermore, by looking at stylistic changes of ceramics as time passes can you really separate (seriate) the ceramics into distinct diagnostic groups (assemblages). A comparison of ceramic artifacts with known dated assemblages allows for a chronological task of these items.[13]The technical approach to ceramic analysis requires a finer examination of the structure of ceramic artifacts and sherds to look for the way to obtain the materials and through this the possible processing site. Key standards are the composition of the clay and the temper used in the production of the article under analysis: temper is a material put into the clay through the initial production level, and it is employed to aid the next drying out process. Types of temper include shell bits, granite fragments and floor sherd items called 'grog'. Temper is recognized by microscopic examination of the temper material usually. Clay identification depends upon an activity of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation. By estimating both temper and clay compositions, and locating a region where both are recognized to occur, an assignment of the material source can be made. From the foundation task of the artifact further investigations can be made in to the site of make.
