Calcium/Strontium/Barium Compounds TRIZ Cases
- Battery Powder Leaching for Selective Aluminum Precipitation
Calcium and fluorine enable selective aluminum precipitation from Li-ion battery leachate, preserving nickel and cobalt for metal recovery.
- Composite Hexagonal Ferrites for High-Permeability RF Resonance
By combining Y-phase and Z-phase ferrites with controlled doping, this case balances high permeability and resonant frequency for RF antennas.
- Acid-Mediated Insoluble Metal Adduct Formation for Solubility Control
Acidic media enables soluble and insoluble metal hydroxides or oxides to form stable insoluble adducts with controlled solubility.
- Calcite-Copolymer Hydraulic Composition for Early Strength
A calcite-copolymer additive maintains low shear viscosity while accelerating hydration and strength gain within 5 to 20 hours.
- Battery Waste Aluminum Removal via Calcium-Fluorine Precipitation
This leaching and neutralization approach precipitates aluminum from battery waste while minimizing nickel and cobalt loss.
- Lithium Extraction from Brine Using Phosphate Precipitation
Phosphate precipitation extracts lithium from high-impurity brine, avoiding the slow solar evaporation process and preventing co-precipitation losses.
