Abstract

The EPR technique has been used to study the behaviour of impurity ions in the course of phase transformations during the crystallization of glass. The paramagnetic ions have been found to be copable of both incorporation into the avaiable phases and creation of their own crystalline phases. It has been established for the first time that during phase transitions there form in certain matrices the paramagnetic defect centres of the free-radical type. They arise due to the break of interionic bonds in glass crystallization.
