Neodymium (III) chloride (NdCl3), or neodymium trichloride, is a purple powder and stable under atmospheric pressure. It is soluble in water, ethanol, ether, chloroform. Its anhydrous form is a mauve-colored powder that easily absorbs the moisture in the air and turns to purple hexahydrate.
Neodymium Chloride mainly used for glass, crystal 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. It is useful in protective lenses for welding goggles. It is also used in CRT displays to enhance contrast between reds and greens. It is highly valued in glass manufacturing for its attractive purple coloring to glass.

Neodymium Chloride Applications:
1. Production of neodymium metal: most common starting compound for production of neodymium metal
2. Lasers and fiber amplifiers: it is a dopant not only of traditional silica-based optical fibers, but of plastic fibers (dopedphotolime-gelatin, polyimide, polyethylene, etc.) as well.
3. Catalysis: used to combine with organic chemicals such as triethylaluminium, 2-propanol, and titanium dioxide
4. Corrosion protection: Neodymium (III) chloride is a corrosive inhibitors which is environment friendly and much less toxic.
5. Labeling of organic molecules: Neodymium has strong luminescence, so neodymium chloride is often used as a source of Nd3+ ions as fluorescent labels in various physical and chemical reactions.
