Thermal properties of oxide glasses: part IV. Induction period of crystallization as a criterion of thermal stability of [M.sub.2]OSi[O.sub.2] glass systems against crystallization

A criterion based on the length of induction period of crystallization was used to evaluate the thermal stability of [M.sub.2]OSi[O.sub.2] (M = Li, Na) glasses against crystallization. It was founded out that the stability of studied glasses against crystallization is [Li.sub.2]O * Si[O.sub.2] <...

Description
Summary:A criterion based on the length of induction period of crystallization was used to evaluate the thermal stability of [M.sub.2]OSi[O.sub.2] (M = Li, Na) glasses against crystallization. It was founded out that the stability of studied glasses against crystallization is [Li.sub.2]O * Si[O.sub.2] < [Na.sub.2]O * Si[O.sub.2]. The results coincide with the order determined by stability criteria based on temperatures and the values of activation energy. A criterion based on the length of induction period enables to discriminate among the thermal stabilities of the silicate glass systems.
