Applications
High purity La2O3 (Lanthanum (III) Oxide or Lanthanum Sesquioxide) is used in ceramics, glass, ferroelectric materials, and optical materials. Lanthanum oxide has p-type semiconducting properties and a band gap of approximately 5.8 eV. Its average room temperature resistivity is 10 kΩ·cm, which decreases with an increase in temperature. La2O3 is commonly used as a host material in making laser gain media. La2O3 powder is also used to synthesize solid state electrolyte garnet LLZO materials, which can be ordered from MSE Supplies.
