Vitrification Ceramics Definition

You can visualize the ceramic as being initially composed of many small grains that tightly pressed together.

Vitrification ceramics definition.

The word ceramic comes from the greek word keramikos which means of pottery. In ceramics porosity is considered an indication of density and therefore strength and durability. Vitrification from vitreum latin for glass is the most important and perhaps the most poorly understood process in ceramics. The toughness strength and translucence of porcelain relative to other types of pottery arises mainly from vitrification and the formation of the mineral mullite within the body at.

State of being vitrified. Vitrification is usually achieved by heating materials until they liquidize then cooling the liquid often rapidly so that it passes. While the earliest ceramics were pottery the term encompasses a large group of materials including some pure elements. A ceramic is an inorganic nonmetallic solid generally based on an oxide nitride boride or carbide that is fired at a high temperature.

Traditional ceramics ceramic materials that are derived from common naturally occurring raw materials such as clay minerals and quartz sand through industrial processes that have been practiced in some form for centuries these materials are made into such familiar products as china tableware clay brick and tile industrial abrasives and refractory linings and portland cement. Mature clays are dense and strong immature ones porous and weak. In the production of ceramics vitrification is responsible for its impermeability to water. Vitrification from latin vitreum glass via french vitrifier is the transformation of a substance into a glass that is to say a non crystalline amorphous solid in the production of ceramics vitrification is responsible for its impermeability to water.

A glass formed in the process of vitrification even in tiny amounts is what holds ceramic materials together. Vitrification is literally turning into glass. Maturity a term used in the ceramics industry to signify the degree of vitrification in a fired clay. Porcelain ˈ p ɔːr s əl ɪ n is a ceramic material made by heating materials generally including a material like kaolin in a kiln to temperatures between 1 200 and 1 400 c 2 200 and 2 600 f.

Porosity is measured by the weight increase when boiled in water. Vitrification definition act or process of vitrifying. Glass in this context is a more or less contiguous amorphous solid region in the ceramic.
