Neodymium ( III) chloride is a chemical compound selected from the group of chlorides.

Production and representation

Neodymium ( III) chloride can be obtained by reacting neodymium ( III) oxide with hydrogen chloride or ammonium chloride.

It can also be synthesized directly from the elements.

Properties

Neodymium ( III ) chloride is a pink to pale violet highly hygroscopic powder that quickly absorbs moisture in air and converts to the hexahydrate. It has a hexagonal crystal structure with space group P63 / m. The hexahydrate is purple and has a monoclinic crystal structure with space group P2 / c. At 160 ° C there is from the crystal water and forms the anhydrous form.

Use

Neodymium ( III) chloride is used as a laboratory chemical and for the preparation of other neodymium compounds. It also serves as a catalyst for organic syntheses. The hexahydrate is mainly used for glass, crystal and capacitors. Colored glass with additions from neodymium chloride shows delicate shades of violet to pure wine red and warm gray. These glasses show unusually sharp absorption bands.
