Abstract

The minerals which are most resistant to natural corrosive media and possess perovskite, zirconolite, fergusonite, and Y-Al garnet type structures are selected on the basis of an analysis of the mineralogical data. The minerals contain elements that are isomorphic to radionuclides appearing in high-level wastes.

Synthesis of the analogs of calcinites, using metallothermal processes in a self-propagating high-temperature synthesis regime, was investigated on model systems in application to the immobilization of calcinates of high-level wastes. Compaction of the analogs of perovskite and zirconolite was investigated most completely, and the effect of various formulations and technological parameters on the process is studied. 3 figures, 2 tables, 6 references.
