Grinding, processing, and sales of single crystal sapphire.

"Sapphire" is a single crystal of alumina (Al2O3) and is a transparent material with high transmittance from ultraviolet light to visible light and infrared light due to its optical properties!

Sapphire, which is also famous as a gemstone, has high transparency across optical properties from ultraviolet rays to visible light and infrared rays. It is often processed into transparent plates to be used as "windows," "glass," or "crystal" in high-end wristwatches. Additionally, it is used in optical components such as sensors and instruments. 【Features】 ■ High Transparency: It can be used for optical windows that utilize infrared rays, as it transmits not only visible light but also infrared rays. ■ Excellent Strength: With a Vickers hardness of 22.5 GPa and a bending strength of 690 MPa, it maintains strength even when processed thinly. ■ High Thermal Conductivity: There are few transparent materials that conduct and dissipate heat effectively. ■ High Heat Resistance: Since sapphire rough stones can only be created at ultra-high temperatures exceeding 2,000°C, it is a material that can withstand high-temperature use. ■ High Corrosion Resistance: It is almost insoluble in acids and alkalis, making it chemically stable. *For more details, please download the PDF or feel free to contact us.
