· VO

Vanadium monoxide (VO) is a transition metal oxide semiconductor with mixed-valence vanadium chemistry, belonging to the broader family of vanadium oxides known for metal-insulator transitions and variable oxidation states. VO is primarily investigated in research and advanced applications requiring tunable electronic properties, including smart windows, thermal sensors, and next-generation energy storage devices. Its notable distinction lies in its temperature-dependent semiconductor behavior and potential for integration into systems where switchable optical or electrical response is advantageous over conventional fixed-property semiconductors.

Regulatory Screening

Environmental

Export Control

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.
