Vitrification Ceramics Definition

In ceramics porosity is considered an indication of density and therefore strength and durability.

Vitrification ceramics definition.

While the earliest ceramics were pottery the term encompasses a large group of materials including some pure elements. Vitrification is usually achieved by heating materials until they liquidize then cooling the liquid often rapidly so that it passes. State of being vitrified. 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.

The word ceramic comes from the greek word keramikos which means of pottery. 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. 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.

Vitrification is literally turning into glass. Vitrification is usually achieved by heating materials until they liquidize then cooling the liquid often rapidly so that it. Porosity is measured by the weight increase when boiled in water. Mature clays are dense and strong immature ones porous and weak.

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

Vitrification from vitreum latin for glass is the most important and perhaps the most poorly understood process in ceramics. Vitrification definition act or process of vitrifying. Glass in this context is a more or less contiguous amorphous solid region in the ceramic.
