Relationship between phase separation and properties in some non-prototype glasses

The microstructure of different samples concerning the matrices of glass-ceramics and non-prototype glasses including slags, frit of aluminate cement additive, glass ionomer cement as well as dolomite phosphate fertilizer were studied by using an X-ray diffractometer and electron microscope. It was revealed that phase separation occured in most of these samples of non-prototype glasses.

The relationship between phase separation and properties, e.g. viscosity and chemical activity of these melts or amorphous solids are discussed. Factors influencing the mechanism of phase separation are estimated.
