sapphire ingot 3inch 4inch 6inch Monocrystal CZ KY method Customizable
Key Features
Exceptional Purity and Quality:
Sapphire ingots are crafted with high-purity aluminum oxide (99.999%), ensuring a flawless monocrystalline structure. The advanced crystal growth techniques employed during manufacturing minimize defects such as pores, chips, and twins, resulting in ingots with minimal dislocations and exceptional performance.
Versatile Sizing and Customization:
Offered in standard diameters of 3 inches, 4 inches, and 6 inches, these ingots are fully customizable to meet the unique requirements of specific applications. Customizations can include diameter, length, orientation, and surface finish, making them suitable for a wide array of industries.
Wide Optical Transparency:
Sapphire exhibits excellent transparency across a broad wavelength range, from ultraviolet (150nm) to mid-infrared (5500nm). This makes it ideal for optical applications requiring high clarity and minimal absorption.
Outstanding Mechanical Properties:
Ranking 9 on the Mohs hardness scale, sapphire is second only to diamond in hardness. This provides exceptional scratch resistance and durability, ensuring a long service life in harsh environments.
Thermal and Chemical Stability:
Sapphire ingots can withstand extreme temperatures of up to 2000°C without compromising their integrity. They are also chemically inert, offering excellent resistance to acids, alkalis, and other corrosive substances.
Manufacturing Processes
Czochralski (CZ) Method:
This technique involves pulling a single crystal from a molten aluminum oxide bath using precise thermal and rotational controls.
Produces high-quality ingots with low defect densities, ideal for applications in semiconductors and optics.
Kyropoulos (KY) Method:
This process grows large, high-quality sapphire crystals by slowly cooling molten aluminum oxide.
KY-grown sapphire ingots are particularly valued for their low stress and uniform properties, making them ideal for high-performance applications.
Both methods are tailored to achieve ingots with superior clarity, minimal dislocation density (EPD ≤ 1000/cm²), and consistent physical properties.
