Product Description

Product Description:Glass-ceramic refers to a base glass with a specific composition added with a crystal nucleating agent (or without a crystal nucleating agent). It is subjected to crystallization and heat treatment under a certain temperature system, and a large number of tiny crystals are uniformly precipitated in the glass to form dense microscopic crystals. A multiphase complex of crystalline and glassy phases. By controlling the types, number and size of crystallites, transparent glass-ceramics, glass-ceramics with zero expansion coefficient, surface-strengthened glass-ceramics, different colors or machinable glass-ceramics can be obtained.

Nanocrystal glass, also known as microcrystalline jade or ceramic glass, is an inorganic non-metallic material. It is a new type of comprehensive glass for building materials. Its scientific name is glass crystal. Glass-ceramic and common glass look very different. It has the dual characteristics of glass and ceramics. The atomic arrangement inside ordinary glass is irregular, which is one of the reasons why glass is fragile. And glass-ceramic, like ceramics, is composed of crystals, that is, its atomic arrangement is regular. Therefore, glass-ceramic has higher brightness than ceramics and stronger toughness than glass.

Product structure:
Microcrystals consist of a glass phase and a crystalline phase. The distribution of the two varies with their proportions.
1. When the proportion of the glass phase is large, the glass phase is a continuous matrix. The crystalline phases are uniformly distributed in isolation.

2. If the glass phase is less, the glass phase is dispersed between the crystal lattices, in a continuous network.

3. If the number of glass phases is very low, the glass phases are distributed among the crystals in a thin film state.

Product features:
High mechanical strength, excellent insulation performance, low dielectric loss, stable dielectric constant, thermal expansion coefficient can be adjusted in a wide range, chemical corrosion resistance, wear resistance, good thermal stability, high operating temperature.

Product applications:
1) β-spodumene glass-ceramic and carbon fiber composite material: strong and toughening effect, a new material in aerospace.

2) Oxygen-nitrogen glass-ceramic: It can be directly micro-crystallized without radiation or adding crystal nucleus, reducing the sintering temperature of silicon nitride crystal and maintaining high-strength β-silicon nitride structure.

3) Cutable mica glass-ceramic: layered structure, good electrical insulation and heat resistance (electronic insulation material).
