Round Sapphire Glass Discs & Plates
The processing difficulty of sapphire glass discs is harder compared to other materials of glass. Because sapphire glass material is a synthetic glass with a hardness second only to diamond. Sapphire glass discs or plates are commonly used as watching windows for watch mirrors. Due to its excellent scratch resistant properties. Sapphire glass discs used for precision instruments must have very precise dimensions. As its dimensional tolerance decreases, the difficulty and cost of processing will correspondingly increase.
The main characteristics of sapphire glass
The main characteristics of sapphire include high hardness, high scratch resistance, high transparency, high temperature resistance, etc., so it is widely used in many high-end applications.
- Scratch resistance: sapphire glass is made of artificial sapphire crystal, with extremely high hardness, can resist scratches and wear in daily useto maintain the clarity and gloss of the glass surface.
- Transparency and optical performance: sapphire glass crystal has a high degree of transparencyand can transmit more light, so that it has a wide range of applications in the field of observation and display. Transmittance band: 185 ~ 5000nm
- High temperature resistance: the melting point of sapphire glass is 2045°C, and the application temperature is generally below 2000°C.
- Pressure resistance: As a kind of high-strength glass, the compressive strength of sapphire glass at room temperature can reach 2.1GPa, so it is used as a viewing window in deep sea diving.
