Properties
Quartz exhibits excellent optical transparency, especially in the UV to IR spectral range, making it ideal for precision optics. It has a very low thermal expansion coefficient, high thermal stability (softening point around 1700°C), and outstanding chemical resistance to most acids and alkalis. Additionally, quartz is mechanically strong, electrically insulating, and highly durable under extreme environmental conditions.
