ABSTRACT
The present study examines the synthesis capacity of powdered Co2Er intermetallic compound in molten eutectic Lithium- Potassium Chlorides mix at constant temperature of 850K when using no-current diffusion saturation technique.
Based on the obtained results, the synthesis modes for the specified composition of powdered Co2Er intermetallic compound were derived. The components’ composition ratio of the reaction mix for the metal phase was established, at which point the synthesis of the specified powdered compound could still be possible. In this case, the powdered compound did not contain admixtures of both the other-phase intermetallic compounds and the unreacted metal substrate powder (Co).
The credibility of the obtained findings was confirmed through X-ray fluorescence and X-ray diffraction analyses using the EDX‑720 energy dispersion X-ray fluorescence spectrometer along with the XDR‑7000S X-ray powder diffractometer.
