Korean J. Met. Mater. 2018;56(3):197-204.   Published online 2018 Mar 6
DOI: https://doi.org/10.3365/KJMM.2018.56.3.197

Abstract
Rhenium coatings were fabricated on a graphite substrate at 1100 and 1250 oC and a molybdenum substrate at 1150 and 1250 oC by chemical vapor deposition (CVD) using ReCl5 precursor, and the effects of deposition temperatures and substrates on microstructure and crystal orientation were investigated. The rhenium coating on graphite..... More

    
Separation of Rhenium (VII) and Vanadium (V) from Hydrochloric Acid Solutions by Solvent Extraction
Thi Hong Nguyen, Hoai Thanh Truong, Man Seung Lee
Korean J. Met. Mater. 2017;55(10):724-731.   Published online 2017 Sep 28
DOI: https://doi.org/10.3365/KJMM.2017.55.10.724

Abstract
The separation of Re(VII) and V(V) by solvent extraction with TBP was investigated by varying the HCl, metal and chloride ion concentrations. Re(VII) was selectively extracted over V(V) from the HCl solution. The highest separation between Re(VII) and V(V) occurred at a concentration of 2.0 M HCl. The extraction reaction..... More

Korean J. Met. Mater. 2017;55(1):53-59.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.53

Abstract
The objective of this study was to obtain basic data for trapping gaseous technetium (Tc) oxide generated from the voloxidation process in spent nuclear fuel pyroprocessing. Rhenium (Re) and Ca(OH)2 were used as surrogates for the technetium and a trapping material, respectively. The trapping characteristics of rhenium oxide were investigated..... More

Korean J. Met. Mater. 2017;55(1):31-38.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.31

Abstract
Solvent extraction experiments were performed with Re(VII) and V(V) from concentrated HCl solutions. In this work, Alamine 336 and LIX 63 were employed as the basic and cationic extractants. At an HCl concentration range from 1 to 5 M, Re(VII) was selectively extracted by Alamine 336, while V(V) was selectively..... More
