Description

A soft, malleable metallic element. Neodymium is a rare-earth element that occurs in the minerals monazite, bastnaesite, cerite and gadolinite. It was discovered by Carl von Welsback in 1885 in Austria. Pure neodymium is a grayish white metal that turns yellowish with exposure to air. The oxide is a pale blue powder that is soluble in water. Neodymium and its oxide are used as a glass colorants for sunglasses and art objects. Neodymium imparts a dichroic property to glass that makes is useful as a filter plate on color television tubes to improve image contrast. Other salts of neodymium have rose and violet colors.
