Product Description
Sapphire Material AL2O3 Monocrystal 80KG 200KG 400KG KY Method LED Semiconductor
Describe of Sapphire:
Sapphire ingots are aluminum oxide crystals, which are used to produce sapphire substrates, the most advantageous upstream raw material for LEDs. Under the rapid development of LEDs, the industry has entered a period of vigorous development in an all-round way. With the full penetration of the LED industry, the demand for the most upstream sapphire products will continue to maintain rapid growth and have broad development prospects. Various artificial growth techniques for sapphire crystals have been continuously developed, and more than ten crystal growth methods have been developed, such as the flame melting method, pulling method, and Kyropoulos method.
The Character of Sapphire:
1. Crystal Structure: Sapphire ingots have a hexagonal crystal structure, characterized by strong anisotropy and high crystalline quality.
2. Transparency: Sapphire is optically transparent in the visible to near-infrared spectrum, making it ideal for optical applications such as lenses, windows, and substrates.
3. Hardness: Sapphire is one of the hardest materials, ranking 9 on the Mohs scale, making it highly scratch-resistant and durable.
4. Chemical Resistance: Sapphire is chemically inert and highly resistant to attack from acids and alkalis, making it suitable for harsh environments.
5. High Thermal Conductivity: Sapphire has excellent thermal conductivity, making it useful in applications requiring good thermal management.
6. Electrical Insulation: Sapphire is an excellent electrical insulator, making it suitable for use in electronic components and high-temperature applications.
7. Wide Bandgap: Sapphire has a wide bandgap, making it suitable for optoelectronic devices such as LEDs, laser diodes, and high-power electronics.
8. Biocompatibility: Sapphire is biocompatible and non-toxic, making it suitable for use in medical implants and devices.
9. Precision Machining: Sapphire ingots can be precisely machined to produce components with tight tolerances and high surface quality.
