Abstract
Sapphire
crystal (Al₂O₃), renowned as the "second hardest natural material" after
diamond (Mohs hardness 9), combines exceptional physical, chemical,
and optical properties. Our state-of-the-art CVD (Chemical Vapor
Deposition) and Pull-Up Growth technologies produce ultra-pure,
defect-free crystals with diameters ranging from 5mm to 300mm,
catering to cutting-edge industries including semiconductors,
consumer electronics, optics, and industrial manufacturing.
