| Abstract Scope |
Technetium (Tc) present in radioactive waste has a long half-life, ~200,000 years, and is environmentally mobile, which poses challenges to manage the long-term dose from exposure. TcS2 has been deemed a potential waste form material though a significant obstacle to progress is the limited synthetic pathways that exist to prepare the material. This has led us to investigate a new synthetic pathway to Tc chalcogenides utilizing the boron-chalcogen mixture (BCM) method as a facile route to synthesize technetium chalcogenide materials. This talk will present the current results of preliminary research on the synthesis of rhenium (Re) chalcogenides using the BCM method as well as thermal analysis and high temperature PXRD performed on the synthesized materials. Plans for the translation of this work to technetium containing systems will also be presented. |
