Description
Application:
Neodymium Oxide,
also called Neodymia, mainly used for glass and capacitors. Colours
glass delicate shades ranging from pure violet through wine-red and
warm gray. Light transmitted through such glass shows unusually
sharp absorption bands. The glass is used in astronomical work to
produce sharp bands by which spectral lines may be calibrated.
Glass containing neodymium is a laser material in place of ruby to
produce coherent light.
