Optical Glass Manufacturing Min 99.99% Lanthanum Oxide

  La₂O₃ is used to make optical glasses, to which this oxide confers increased density, refractive index, and hardness. Together with oxides of tungsten, tantalum, and thorium, La₂O₃ improves the resistance of the glass to attack by alkali. La₂O₃ is an ingredient for the manufacture of piezoelectric and thermoelectric materials. Automobile exhaust-gas converters contain La₂O₃. La₂O₃ is also used in X-ray imaging intensifying screens, phosphors as well as dielectric and conductive ceramics. Gives off bright glow.
