Praseodymium and neodymium oxide, molecular formula (PrNd)xOy, appears as gray or tan powder. It easily absorbs water and air. It must be stored in a dry place and cannot be left in the open air. For deep processing and glass, ceramics, magnetic materials, etc. Praseodymium and neodymium oxide gray powder is the raw material of metal praseodymium and neodymium (i.e. praseodymium and neodymium alloy). After praseodymium and neodymium oxide is melted and processed at high temperature, metal praseodymium and neodymium is formed.
For construction ceramics and ceramics for daily use, which blend with the ceramic enamel glaze, but also can be used alone as underglaze pigment used to make permanent magnets. The magnets can be processed into various shapes. Widely used in various types of electronic devices and motor; for petroleum cracking. Praseodymium neodymium enrichment in the form of added oil cracking catalyst Y-type zeolite molecular sieves, can increase the activity, selectivity and stability of the catalyst; for abrasive polishing; also for fiber optic fields.
