USE
Lanthanum oxide (La<sub>2</sub>O<sub>3</sub>) has a melting pointof 2250°C, is soluble in acids, and very slightlysoluble in water. This oxide of a rare earth elementoccurs in monazite and bastnasite. It ismarketed as the oxide or as other salts such asthe oxalate, nitrate, or hydrate. It quicklyabsorbs water and CO<sub>2</sub> from the atmosphere.Its chief use is as an ingredient in nonsilica,rare element optical glass with oxides of tungsten, tantalum, and thorium. Lanthanumincreases refractive index, decreases dispersion,and is also used in x-ray image intensifyingscreens that speed up x-ray exposure asmuch as two to ten times so that diagnosticdosages may be reduced by as much as 80%with fewer retakes. It is also used in bariumtitanate capacitors.
