Lanthanum Oxide/Hydroxides TRIZ Cases
- La2O3-rGO Humidity Sensor Composite for Fast Room-Temperature Sensing
Combining hygroscopic La2O3 with conductive rGO enables fast, stable humidity sensing across a wide range at room temperature.
- Solid-State Electrolyte Recovery by pH-Controlled Metal Separation
Sequential acid leaching and pH-controlled precipitation separate lanthanum, zirconium, and lithium from all-solid-state batteries.
- Rare Earth Oxide Calcination with Ammonia and Carbon Recycling
Microwave calcination paired with CO2 and ammonia recycling shortens rare earth oxide processing and improves carbon and ammonia use.
- Composite Oxide Ruthenium Catalyst for Low-Pressure Ammonia Synthesis
A composite oxide carrier stabilizes ruthenium dispersion to raise ammonia yield under lower temperature and pressure conditions.
- Cerium Polishing Powder Waste Leaching for Gradient Rare-Earth Recovery
Two-step acid leaching with alkali activation separates La-rich liquor and high-purity CeO2 from cerium polishing powder waste with low pollution.
- Nanostructured Lanthanum Oxide Sensor for Fast Humidity Detection
Lanthanum oxide thin films lower electrical resistance via hole density changes, bypassing slow capacitive readout circuits.
- Rare Earth Oxide Slurry with Acetylene Glycol Adduct
Acetylene glycol-ethylene oxide adduct controls nucleation to produce rare earth oxide particles below 50 nm with sharp distribution.
- Selective Flocculation for Rare Earth Separation from Kaolinite
A selective flocculation polymer aggregates kaolinite particles in aqueous suspension, leaving rare earth compounds deflocculated for extraction.
- Black Mixed Oxide Pigment Eliminating Chromium and Cobalt
A black mixed oxide pigment composed of lanthanum, manganese, and copper oxides provides a nonmagnetic, insulating material for industrial applications.
- Homogeneous Catalysts via Solution Combustion Synthesis
Solution combustion synthesis creates homogeneous metal oxide catalysts with tailored active species distribution.
