CRYSTALLIZATION OF GLASSES IN SYSTEM PbO-GeO <sub>2</sub>
Conditions and kinetics crystallization of glasses insystem PbO-GeO2 are studied at heating and in isothermal conditions. Thermal stability is investigated and the sequence of phase transformations of three germanium glasses a containing 30, 50 and 60 pier is certain. % PbO, energy of activation is calculated. It is shown, that conditions of reception of glass influence process of its crystallization. Process of crystallization of glass in an interval of temperature 450 - 650 0С can be considered as a perspective way of reception of ceramic materials in this system.
