Abstract

Conditions required for the isolation of Tc-bearing wastes include their incorporating into metallic alloys and placement in underground waste repositories under reduced conditions. The paper reports means of synthesizing these matrices and distinctive structural features of samples produced by self-propagating high-temperature synthesis (SHS).
