Glass-ceramic refers to the addition of certain nucleating substances to the glass, and uniformly deposits a large number of minute crystals in the glass by heat treatment, light irradiation, or chemical treatment to form a dense microcrystalline phase and a multiphase of the glass phase. Complex. By controlling the number and size of crystallites, transparent glass-ceramics, glass-ceramics with a coefficient of expansion of zero, surface-enhanced glass-ceramics, different colors or machinable glass-ceramics can be obtained.
CRYSTOE and NEOPARIES are also known as microcrystalline jade or ceramic glass. It is an inorganic non-metallic material. It is a comprehensive glass, a new type of building material that has just been developed in foreign countries. Its scientific name is glass crystal. Glass-ceramics and our common glass look very different. It has the dual characteristics of glass and ceramic. The atomic arrangement inside the ordinary glass is not regular, which is one of the reasons for the fragility of the glass. Microcrystalline glass, like ceramics, consists of crystals, that is, its atomic arrangement is regular. Therefore, glass-ceramics have higher brightness than ceramics and are stronger than glass.
