Characteristics of alumino-borosilicate glasses
Aqueous alteration of Silicate - Glass Case of Nuclear Glasses

The term “glass” applies to compounds that, after melting and cooling, form a non-crystalline solid that partially retains the structural disorder of the liquid: the material is therefore in a thermodynamically metastable state known as the “glass state” . This gives rise to two key concepts: glass must exhibit viscous behavior, and the cooling rate of the liquid must be sufficiently high to “freeze” it without allowing the material time to crystallize. Glass is thus considered a frozen supercooled...
