Size( D=diameter * T=thickness ), (L=length, W=width, T=thickness)
Sapphire Glass (Synthetic Sapphire) is an exceptionally hard, transparent material made from pure single-crystal aluminum oxide (Al₂O₃).
Key Characteristics:
-
Extreme Hardness: Mohs scale 9, highly scratch-resistant.
-
Excellent Optical Clarity: High transparency from UV to IR wavelengths.
-
Superior Durability: Chemically inert, thermally stable (melts at ~2053°C), and mechanically strong.
-
Electrical Insulator: Excellent dielectric properties.
Common Uses: Watch crystals, smartphone camera covers, LED/semiconductor substrates and military/optical windows.
Note: Despite being called “glass,” it is a single crystal, not an amorphous glass.
