Neodymium (III) Chloride:

1. Characteristics:

• Chemical Name: Neodymium (III) Chloride (NdCl₃), also known as neodymium trichloride.
• Appearance:
  • Anhydrous form: Mauve-colored powder, hygroscopic, absorbing moisture to form purple hexahydrate.
  • Stable under atmospheric pressure.
• Solubility: Soluble in water, ethanol, ether, and chloroform.

2. Applications:

• Glass and Crystals:
  • Adds delicate hues ranging from pure violet to wine-red or warm gray.
  • Used in specialized glass manufacturing to create attractive and functional coloring.
  • Provides sharp absorption bands, beneficial for applications like protective lenses for welding goggles and CRT displays, enhancing contrast between reds and greens.
• Neodymium Metal Production:
  • Serves as the most common starting compound for synthesizing neodymium metal.
• Lasers and Fiber Amplifiers:
  • Acts as a dopant in both silica-based and plastic optical fibers, improving performance in lasers and amplifiers.
• Catalysis:
  • Combines with organic chemicals (e.g., triethylaluminum, 2-propanol, titanium dioxide) to enhance catalytic processes.
• Corrosion Protection:
  • Functions as an eco-friendly, low-toxicity corrosion inhibitor.
• Organic Molecule Labeling:
  • Provides Nd³⁺ ions for luminescence-based fluorescent labeling in chemical and physical reactions.
