High-Temperature Stability: Melting point ~2135°C, suitable for extreme thermal environments.
Mechanical Strength: High hardness (Mohs 8), excellent wear resistance.
Chemical Inertness: Resistant to acids, alkalis, and oxidation at elevated temperatures.
Thermal Properties: Low thermal expansion coefficient, high thermal conductivity, and superior thermal shock resistance.
Electrical Insulation: High electrical resistivity and low dielectric loss, ideal for electronic substrates.
Optical Transparency: Single-crystal forms exhibit transparency in UV to mid-IR ranges, useful for optical windows
