Application

When heated in the presence of water vapor, lanthanum oxochloride is formed:

LaCl3 + H₂O→LaOCl + 2HCl

Heating with glass at elevated temperatures also forms oxochloride:

LaCl3 + SiO2→2LaOCl + SiCl4

Lanthanum chloride reacts with hydrogen sulfide when heated at 1100°C, forming lanthanum sulfide:

2LaCl3 + 3H2S→La2S3 + 3H2S

Reactions with ammonia and phosphine at elevated temperatures yield lanthanum nitride and phosphide, respectively:

LaCl3 + PH3→LaP + 3HCl

Lanthanum chloride is reduced to lanthanum metal when heated with an alkali or alkaline earth metal at temperatures above 1000°C:

LaCl3 + 3Li→La + 3LiCl
