Product Name:Praseodymium hydride
English Name:Praseodymium hydride
CAS No.:13864-03-4
Aliases:Praseodymium trihydride, Praseodymium(III) hydride
Molecular Formula:H3Pr
Physical Properties:Black to gray-black powder or lump solid with a density of approximately 6.1 g/cm³. It is relatively stable in dry air but rapidly hydrolyzes in moist air or upon contact with water, forming praseodymium hydroxide and releasing hydrogen gas. It decomposes into metallic praseodymium and hydrogen when heated to approximately 350°C. It should be stored sealed in an inert atmosphere.
Uses:Used as a hydrogen storage material and hydrogen generating agent, and for preparing high-purity metallic praseodymium. It also serves as a reducing agent in organic synthesis and as an important precursor for rare earth catalysts, with applications in electronic materials and special alloys.
Technical Specifications:
Formula: H3Pr
Molecular weight: 143.93
Purity: ≥99.9%
Appearance: black to gray-black powder or lump
Storage: sealed, dry, inert atmosphere protection
