Vanadium Oxides TRIZ Cases
- Passive Thermal Switch Coating for Solar Reflection and Emissivity Switching
A layered VO2 and dielectric coating cuts solar absorption while switching mid-infrared emissivity for passive radiative cooling.
- Vanadate Solution Purification by Selective Molybdenum Precipitation
Portioned calcium hydroxide addition at pH 6-7 precipitates molybdenum before vanadium, enabling vanadium chemicals below 500 ppm Mo.
- Vanadium Oxide Recovery from Gasifier Slag via Alkali Roasting
Alkali roasting and selective precipitation isolate vanadium pentoxide from refractory gasifier slag, overcoming low purity caused by silica interference.
- Lithium-Doped Copper Vanadium Oxide for Negative Thermal Expansion
Dissolving lithium atoms in a copper vanadium composite oxide improves negative thermal expansion while maintaining low raw material costs and water resistance.
