1. Isotropic
The molecular arrangement of glass is irregular, and its molecules exhibit statistical uniformity in space. In an ideal state, the physical and chemical properties of homogeneous glass, such as refractive index, hardness, elastic modulus, coefficient of thermal expansion, thermal conductivity, conductivity, etc., are the same in all directions.
2. No fixed melting point
Because glass is a mixture and non crystalline, it has no fixed melting and boiling point. The transformation of glass from solid to liquid occurs within a certain temperature range (i.e. softening temperature range), which is different from crystalline substances and does not have a fixed melting point.
3. Metastability
Glassy materials contain higher internal energy than crystalline materials, and their energy is between the molten and crystalline states, belonging to a metastable state. From a mechanical perspective, glass is an unstable high-energy state, such as a tendency to transition to a low energy state, which means there is a tendency for crystallization. Therefore, glass is a metastable solid material.
4. Gradual and reversible properties
The process of a glassy substance transitioning from a molten state to a solid state is gradual, and the changes in its physical and chemical properties are also continuous and gradual. The transition of glassy substances from a molten state to a solid state occurs over a wide temperature range. As the temperature gradually decreases, the viscosity of the glass melt gradually increases, and ultimately forms solid glass. However, no new phases are formed during the process.
