What are the production methods of lanthanum oxide?
Production Methods of Lanthanum Oxide (La₂O₃)
1. Industrial Mainstream: Solvent Extraction + Precipitation-Calcination (bulk production, 3N/4N grade)
Rare earth feed liquid (monazite/bastnaesite leachate, Ce removed) goes through multi-stage solvent extraction to separate La from Pr, Nd and other rare earths.
Purified lanthanum nitrate/chloride solution → precipitate with oxalic acid / ammonium bicarbonate → lanthanum oxalate or lanthanum carbonate.
Filter, wash, dry, then calcine at 800–1000 ℃ in air to get La₂O₃.
2. Thermal Decomposition of Lanthanum Hydroxide (Lab & small batch)
3. Sol-Gel Method (High-purity, nano powder, uniform particle size)
Feature: good homogeneity, fine particle; high cost, not for large tonnage.
4. Spray Pyrolysis (Spherical powder for advanced ceramics / coating)
5. Hydrothermal Method (Controlled morphology, ultrafine powder)
6. Microwave Calcination (Improved calcination route)
Extraction + oxalate/carbonate precipitation + calcination
Nano / high purity: Sol-gel, hydrothermal
Spherical powder: Spray pyrolysis
