The glassy substance is generally obtained by the rapid cooling of the melt. When the transition from the molten state to the glass state, the viscosity increases sharply during the cooling process, and the particles do not have a regular arrangement to form crystals, and no latent heat of crystallization is released. Therefore, the glass state The material contains higher internal energy than the crystalline material, and its energy is between the molten state and the crystalline state and belongs to a metastable state. From a mechanical point of view, glass is an unstable high-energy state, such as the tendency of low-energy state transformation, that is, the tendency of crystallization, so the glass is a metastable solid material.
