The main material of the sapphire mobile phone panel is sapphire single crystal, which has a hardness of nine, high temperature resistance, high strength and abrasion resistance, more wear-resistant and zero scratch, and a smaller friction coefficient, which is the embodiment of high-end mobile phones. Mainly used in various mobile phones and various touch screen panels.
Sapphire watch mirror polishing
The main chemical composition of the sapphire watch mirror is aluminum oxide (AL2O3), with a Mohs hardness of 9, second only to diamonds. It has extremely high strength and abrasion resistance, which effectively prevents daily wear and hard objects. Stable chemical properties, resistance to strong acid and alkali corrosion, not easy to reduce moisture, melting point 2050 ℃, boiling point 3000 ℃, maximum working temperature close to 2000 ℃, high thermal conductivity and heat dissipation effect faster. Mainly used in the mirror of high-end watches, such as Iwatch.
Sapphire substrate polishing
The sapphire substrate is an ingot produced by the alumina trioxide AL2O3 raw material through a crystal growth furnace. , Melting point is 2050 ° C; hardness reaches 9th grade, second only to diamond hardness. Sapphire substrates are mainly used in LEDs, such as LED energy-saving lighting, LED landscape decoration, LED car lights, traffic lights, and so on. 。 See more polishing cases .
