Vitrification Definition Ceramics

Vitrification from vitreum latin for glass is the most important and perhaps the most poorly understood process in ceramics. Ceramics 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. It is possible to retain the amorphous phase at room temperature by fast cooling.

Vitrification definition ceramics.

Vitrification is the formation of glass accomplished in this case through the melting of crystalline silicate compounds into the amorphous noncrystalline atomic structure associated with glass. Bodies do not have specific vitrification points. Vitrification is a process. In the production of ceramics vitrification is responsible for its impermeability to water.

Vitrify definition is to convert into glass or a glassy substance by heat and fusion. 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. The vitrification generally results in reducing the porosity due to viscous flow.

Environmental monitoring and characterization 2004. As ceramics are crystalline materials virtification in ceramics refers to conversion from crystalline to amorphous nature during heating. Vitrification vitrification is another type of containment wherein the contaminated matrix is heated to high temperatures to melt the porous media i e the silica components which subsequently cools to form a glassy impermeable block. In silicate based ceramics bonding and consolidation are accomplished by partial vitrification.

Glass claybodies and glazes vitrify but in ceramicsuse of the term focuses most on clay bodies. A glass formed in the process of vitrification even in tiny amounts is what holds ceramic materials together. Vitreous refers to glassy or amorphous state. Porcelain has been described as being completely vitrified hard impermeable even before glazing white or artificially coloured translucent except when of considerable thickness and resonant.

Vitrificationis the solidification of a melt into a glass rather than a crystallinestructure crystallization.
