Description
As a premier sapphire boule supplier and sapphire ingot distributor, we specialize in providing the fundamental material for high-tech industries: the sapphire crystal ingot. Also known as a sapphire boule or sapphire ingot, this single-crystal aluminum oxide (Al2O3) is the essential starting block for producing high-performance components.
Our core product is a high purity, low dislocation sapphire ingot, grown with precision using advanced methods like the Kyropoulos (KY) or Heat Exchanger Method (HEM). This ensures exceptional crystalline perfection, optical homogeneity, and superior mechanical strength. We offer specialized orientations, including the industry-standard c-axis sapphire ingot, tailored for specific wafer cutting plans to maximize yield and performance.
These high-quality sapphire ingot forms serve as the critical substrate material for a wide range of applications. They are primarily used in manufacturing LED wafers, enabling the solid-state lighting revolution. Furthermore, they are indispensable for optical windows, laser systems, and sensitive semiconductor (GaN-on-Sapphire) devices, where outstanding durability, scratch resistance, and thermal stability are non-negotiable. By supplying a reliable and consistent sapphire crystal ingot, we empower innovators across the optoelectronics and advanced manufacturing sectors.
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.
