What is microcrystalline glass ceramic

---

Microcrystalline glass ceramic is a new type of inorganic non-metallic material that lies between glass and ceramics. It is formed by controlled nucleation and crystallization treatment of a specific composition of base glass, resulting in a polycrystalline solid material containing a large number of microcrystalline and glass phases.

Characteristics and advantages
Microcrystalline glass ceramics combine the advantages of glass and ceramics, and have the following unique properties:

1. High strength and hardness: Microcrystalline glass ceramics have significantly higher mechanical strength and hardness than ordinary glass, and can withstand higher stresses.
2. Adjustable thermal expansion coefficient: Its thermal expansion coefficient can be adjusted within a large range, and the thermal expansion coefficient of certain types of microcrystalline glass ceramics (such as lithium aluminum silicate microcrystalline glass) can even approach zero.
3. Chemical corrosion resistance: It has good corrosion resistance to acids, bases, and organic solvents.
4. Good electrical insulation: Microcrystalline glass ceramics are an excellent high-temperature electrical insulation material with high insulation strength.
5. Excellent heat resistance: The long-term use temperature of microcrystalline glass ceramics can reach 800 ℃, and it has excellent heat shock resistance.
6. Machinability: Microcrystalline glass ceramics can be processed using metal processing tools for drilling, turning, milling, etc., with high processing accuracy.

Application area
The excellent properties of microcrystalline glass ceramics make them widely used in multiple fields:

1. Construction industry: Used for decorative ceilings, exterior wall decoration, etc., it is highly favored for its beauty and durability.
2. In the field of electronics and microelectronics: used for manufacturing electronic components such as circuit boards and charge storage tubes.
3. Aerospace field: As a structural material used in aircraft, rockets and other spacecraft, it has high strength, low thermal expansion coefficient and good heat resistance.
4. Medical field: used for bone repair materials, artificial joints, oral implants, etc., due to its good biocompatibility and corrosion resistance.
5. Precision instruments: Fixed support components used for manufacturing optical equipment, electronic devices, and precision measuring instruments.
6. Chemical industry: used for manufacturing high-temperature and corrosion-resistant reactors and pipelines.

Microcrystalline glass ceramics, as a high-performance composite material, have shown great potential for applications in many fields due to their unique physical and chemical properties.
