Vitrification Ceramics Definition

Vitrification is literally turning into glass.

Vitrification ceramics definition.

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. A glass formed in the process of vitrification even in tiny amounts is what holds ceramic materials together. Mature clays are dense and strong immature ones porous and weak. The word ceramic comes from the greek word keramikos which means of pottery.

The ultimate purpose of firing is to achieve some measure of bonding of the particles for strength and consolidation or reduction in porosity e g for impermeability to fluids in silicate based ceramics bonding and consolidation are accomplished by partial vitrification vitrification is the formation of glass accomplished in this case through the melting of crystalline. 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. 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.

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. In the production of ceramics vitrification is responsible for its impermeability to water. Vitrification from vitreum latin for glass is the most important and perhaps the most poorly understood process in ceramics. 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.

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. Glass in this context is a more or less contiguous amorphous solid region in the ceramic. Maturity a term used in the ceramics industry to signify the degree of vitrification in a fired clay. In ceramics porosity is considered an indication of density and therefore strength and durability.

Vitrification is usually achieved by heating materials until they liquidize then cooling the liquid often rapidly so that it. You can visualize the ceramic as being initially composed of many small grains that tightly pressed together. Porosity is measured by the weight increase when boiled in water.
