Vanadium Compounds TRIZ Cases
- Calcium-Modified Copper Vanadium Oxide for Negative Thermal Expansion
Calcium incorporation improves copper vanadium oxide negative thermal expansion, enabling low- or zero-expansion composites for practical use.
- Spent Catalyst Metal Recovery via Potassium Carbonate Roasting
Potassium carbonate roasting and water leaching recover molybdenum and vanadium from spent supported catalysts with lower process complexity.
