Jawaban singkat
Vanadium Dioxide (VO2) is the thermochromic smart-glazing route in this material set. Its temperature-dependent phase transition, transition temperature, hysteresis, optical modulation, and switching durability require final-stack validation.
Bukan apa
- Vanadium Dioxide is VO2, not V2O3, V2O5, or V4O7; oxidation state and phase are part of its switching identity.
When Not to Use It
- Do not use VO2 when only static NIR attenuation is required and thermochromic transition behavior, hysteresis, or switching durability cannot be managed.
Intrinsic Screening Summary
- Identity screen
- VO2; Vanadium dioxide phase-transition oxide particles
