General description

Lanthanum(III) chloride hydrate is a highly water-soluble crystalline solid widely used in catalytic processes and as a dopant in the production of phosphors and ceramics.

Application

Lanthanum(III) chloride hydrate can be used:
  • As a precursor to synthesize La-based nanostructures.
  • As a dopant to fabricate ZnO nanoparticles with enhanced optical particles.
  • To synthesize Fe–La composite (hydr)oxides for arsenic removal from water.
  • Tofabricate lanthanum hexaboride (LaB6) powders forultra-high-temperature ceramics.
