FIELD: metallurgy.SUBSTANCE: powder synthesis is performed in a sealed vessel in argon environment under temperature of 850 K. Reaction mixture is molten salts containing the following, wt %: neodymium 24-26, nickel 23, eutectic of lithium chloride and potassium chloride - the rest. Neodymium is introduced in reaction mixture resulting from corrosion of massive metal in molten salts. Reaction mixture is exposed under 850 K for 2 hours, and then temperature is increased to 1170 K, and it is exposed for 3 hours. Alloy is subjected to hydrotreating under salts dissolution in water, and powder NdNiis dried under temperature below 320 K in vacuo.EFFECT: intermetallic compound powder is characterised by high pureness, high sorption properties, capability of reversible absorption of hydrogen great quantities.1 dwg |
