What are the applications of machinable glass ceramics

---

Machinable glass ceramics, as a high-performance advanced material, play a key role in multiple high-precision industrial and technological fields due to their unique mechanical properties, thermal stability, and processability.

Core characteristics and product advantages of machinable glass ceramics
Machinable Glass Ceramics is a microcrystalline glass material made through a special heat treatment process, which combines the molding freedom of glass with the excellent properties of ceramics. Its main advantages include:

1. Excellent machinability: Standard metal processing tools can be used for precision machining such as turning, milling, drilling, and tapping, without the need for post sintering treatment, greatly reducing the manufacturing cycle.
2. Excellent thermal stability: low coefficient of thermal expansion, strong heat shock resistance, wide operating temperature range (-200 ℃ to 850 ℃).
3. High insulation and vacuum density: does not release gas, suitable for high vacuum environments, stable dielectric constant.
4. Good chemical stability: acid and alkali corrosion resistance, anti-aging, long service life.
5. High dimensional stability: The mechanical strength is better than ordinary glass, and it will not deform after long-term use.
