Sapphire
Sapphire has the best surface hardness and chemical inertness of all anisometric crystal with low friction coefficient、excellent optics、electric insulativity、high temperature resistant(1600 ℃) and 8 times more abrasion resistance than steel. Due to the unique physical properties and excellent wide range optical transmittance(170–5500 nm), Sapphire applied field: Window- better corrosion resistance than quartz under plasma processing. Analytical Chemistry- used in spectroscopy、ICAP and other devices Sapphire provides UV transmission、durability and reduce contamination much better than quartz. Medical use: highly used for laser surgery and endoscope
