The stability of

Glassy substance is usually by the molten body fast cooling and get, from molten glass state transition, the cooling process of viscosity increases sharply, too late to do regular arrangement of particles and form crystal, no release of latent heat of crystallization, therefore, glassy state substance than amorphous contained more internal energy, the energy between molten and amorphous, belongs to the metastable state.From the point of view of mechanics, glass is a kind of unstable high-energy state. For example, there is a tendency of low-energy state transformation, that is, there is a tendency of crystal disintegration. Therefore, glass is a metastable solid material.
