Description

A study was made on the effect on vitrification parameters on heterogeneous phases, formed by platinum group metals (Ru, Rh, Pd) in phosphate and borosilicate melts under laboratory conditions, when simulating the process of high-level liquid wastes solidification in induction furnace with cold crucible. It is shown that local temperature of dispersed particles will dictate their phase composition, density and finally the possible rate of sedimentation and accumulation on crucible bottoms. 8 refs.; 4 tabs
