Features Of Glass Ceramic
Low-expansion glass ceramic is a high-quality material used in the manufacture of high-precision optical components. Low-expansion glass-ceramic is an emerging class in recent years. Its low expansion coefficient and thermal stability have gained wide use and attention.
Features of glass ceramic:
- Low expansion coefficient: The expansion coefficient of low-expansion glass-ceramic is very low, 1/10-1/20 of aluminosilicate glass. It is relatively close to the thermal expansion coefficient of metal.
- It has excellent low expansion performance and high temperature change resistance. This allows it to work stably in environments with large temperature changes.
- High thermal stability: The thermal expansion coefficient is very low, and the thermal stability is very high. It can withstand high temperature environments and is not easy to deform or crack.
- Good optical properties: The refractive index and dispersion index are relatively small, and the transparency is high. Therefore, it can be used to manufacture optical devices.
- Easy to process: Low-expansion glass ceramic materials are hard and brittle but easy to machine. They can be processed by grinding, polishing, electrolytic processing and other ways to make devices of various shapes. Welcome inquiry.
