· JVASP-51027· VHO2

VHO2 is a vanadium oxide ceramic compound, likely in the VO2 family, known for its temperature-dependent phase transition behavior. This material exhibits dramatic changes in electrical and optical properties around its metal-insulator transition temperature, making it valuable for smart coatings, thermal switching devices, and adaptive optical applications where controllable response to temperature is required. Its notable advantage over conventional passive ceramics is this active, reversible switching capability, which enables self-regulating thermal management and dynamic optical control without external power.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
