Neodymium Oxide (Nd2O3) Typical Applications
a) Used in ceramic capacitors, color TV tubes, high temperature glazes, coloring glass, carbon-arc-light electrodes, and vacuum deposition.
b) Neodymium(III) oxide is used to dope glass, including sunglasses, make solid-state lasers, and to color glasses and enamels. Neodymium-doped glass turns purple due to the absorbance of yellow and green light, and is used in welding goggles. Some neodymium-doped glass is dichroic; that is, it changes color depending on the lighting. One kind of glass named for the mineral alexandrite appears blue in sunlight and red in artificial light.
c) Neodymium(III) oxide is also used as a polymerization catalyst.
