VSi2 Vanadium Disilicide Powder CAS 12039-87-1

Vanadium Disilicide (VSi₂) is a high-performance intermetallic compound valued for its exceptional thermal stability (melting point ~1670°C), semiconductor properties, and oxidation resistance. This gray crystalline material combines vanadium’s strength with silicon’s thermal conductivity, making it ideal for high-temperature electronics, energy systems, and wear-resistant industrial applications.

High-Temperature Stability: Maintains performance up to 1200°C in oxidizing atmospheres.
Oxidation Resistance: Forms protective SiO₂/V₂O₅ layers at elevated temperatures.
Semiconductor Properties: Tunable electrical behavior for electronic applications.
Lightweight Design: Lower density compared to traditional refractory metals.
