Features of Compactibility and Consolidation of Workpieces Made of Mechanosynthesized Dysprosium Molybdenum Powder

Abstract—Gadolinium molybdate powder is produced by a mechanochemical method from a stoichiometric mixture of molybdenum oxide and dysprosium oxide. Using the XRF, TEM, and SEM methods, it has been shown that, during mechanochemical treatment for 30 min, owing to the occurrence of mechanochemical reactions between the initial powders, a fine powder of the Dy₂MoO₆ compound is formed, containing up to 8% Dy₂(MoO₄)₃. The technological properties (fluidity, compactibility) of mechanically synthesized dysprosium molybdate powder, as well as its microstructure after sintering, have been studied.
