Powder Co2Er Intermetallic Compound Synthesis Conditions in a Halide Melt

The no-current diffusion saturation method is used to study the possibility to synthesize a powder Co 2 Er intermetallic compound in the molten eutectic mixture of lithium and potassium chlorides at a fixed temperature of 850 K. Based on the results obtained, the conditions of synthesizing the powder Co 2 Er intermetallic compound of a given composition are determined. The range of metallic-phase component blending ratios for a reaction mixture is determined; within this range, the powder compound free from impurity intermetallic compounds and unreacted base metal (powder cobalt) can be synthesized. The reliability of the results obtained is confirmed by X-ray fluorescent and X-ray diffraction analyses using an EDX-720 energy dispersive X-ray fluorescent spectrometer and an XRD-700S diffractometer, respectively.
