Didymium Oxide (PrNd)xOy CAS 11141-21-2 For Electrolytic Preparation Of Pr-Nd Metal
Name: Didymium oxide, Praseodymium-Neodymium oxide CAS: 11141-21-2
Molecular formula: (PrNd)xOy Molecular weight: 666.29
Description: Didymium oxide, appearance is gray or brown powder, easy to absorb water and inhale, it must be stored in a dry place, not in the open air. Didymium oxide is the raw material of praseodymium and neodymium (namely praseodymium and neodymium alloy). Didymium oxide are melted at high temperature to form metal praseodymium and neodymium. In the process of rare earth electrolysis, the requirements for the physical properties of didymium oxide are as follows: the dissolution speed of didymium oxide in the electrolyte is fast, the furnace bottom precipitation is less; the flying loss is less, the loss of didymium oxide is low; the wear index is small, the strength is large, and the particles are less broken in the process of screening, mixing, transportation, loading and unloading; the particle fluidity is good. The physical properties of didymium oxide are mainly characterized by specific surface area, particle size and wear index.
