2. Product & Compony Description

2.1 Product Description:

This sapphire monocrystal is composed of 99.999% pure Aluminum Oxide (Al2O3), ensuring minimal impurities and defects. The KY method of growth allows for larger crystal sizes and improved uniformity, making it suitable for high-performance applications. Sapphire ingots are typically used as raw materials for further processing. These sapphire rods and sapphire ingots are uniformly shaped, usually as cylinders. The most sapphire crystal grows in A-axis, and the most widely used sapphire substrate in the LED market is its C-plane (0001). Therefore, it is necessary to drill the c-plane sapphire ingot from the side of the crystal. As one of professional sapphire ingot manufacturers, ZMSH provides sapphire rods and ingots with ground surfaces for further processing and polishing. They are cored from high-grade Kyropoulos grown boules. We supply dia. 2-inch to 8-inch sapphire rod and ingot with any orientation and custom specifications. Flats are available upon request.

The material features:

• Color: Typically colorless or slightly blue, depending on the specific conditions of growth.
• Hardness: Rated 9 on the Mohs scale, providing excellent scratch resistance.
• Transparency: High optical clarity across a wide range of wavelengths.
• Thermal Conductivity: Exceptional thermal properties, allowing for efficient heat dissipation.
