Vitrification Definition Ceramics

In the production of ceramics vitrification is responsible for its impermeability to water.

Vitrification definition ceramics.

As ceramics are crystalline materials virtification in ceramics refers to conversion from crystalline to amorphous nature during heating. Environmental monitoring and characterization 2004. 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. Vitrify definition is to convert into glass or a glassy substance by heat and fusion.

Vitrification from vitreum latin for glass is the most important and perhaps the most poorly understood process in ceramics. Vitrificationis the solidification of a melt into a glass rather than a crystallinestructure crystallization. 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. Bodies do not have specific vitrification points. 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. A glass formed in the process of vitrification even in tiny amounts is what holds ceramic materials together.

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. The vitrification generally results in reducing the porosity due to viscous flow. Vitreous refers to glassy or amorphous state. It is possible to retain the amorphous phase at room temperature by fast cooling.
