Properties and behavior of the platinum group metals in the glass
Two types of platinum group metal particles were found in borosilicate nuclear waste glasses: needle-shaped RuO 2 particles and spherical PdRh x Te y alloys. They form a dense sediment of high electrical conductivity and relatively high viscosity at the bottom of the ceramic melting furnace. The sludge shows a non-Newtonian flow behavior.
