| titleOfInvention | Preparation method of magnesium praseodymium alloy with high praseodymium content and fused salt electrolysis thereof |
| abstract | The invention provides a preparation method of a magnesium praseodymium alloy with high praseodymium content and fused salt electrolysis thereof. In an electrolytic furnace, LiCl-KCl-MgCl2-PrCl3 is an electrolytic system; the mass percents of electrolytes are as follows: 44-45%, 44-45%, 8-9% and 1-4%; the electrolytes are heated to the temperature of 630 DEG C for fusing; metal tungsten or molybdenum is used as a working electrode, graphite is an auxiliary electrode and 1wt% of silver or silver chloride as a reference electrode; a potential valve is controlled about-1.85V at the electrolytic temperature of 630 EDG C; electrolysis is carried out for 180 minutes; magnesium praseodymium alloy is deposited in a fused salt electrolytic cell near the working electrode, wherein the mass percent of the praseodymium is 9.7-23.2% and the balance of magnesium. Any metal needs not to be used as a raw material, but metal chloride is completely adopted to be used as the raw material; the magnesium praseodymium alloy with different components and high praseodymium content can be obtained through controlling electrolyte proportion; the mass percent of the praseodymium in the alloy is 9.7-23.2%; and the whole process is simple, low in equipment and experimental conditions and less in energy consumption and pollution. |
