Keywords:high level liquid waste, vitrification, platinum group elements, sedimentation

Sedimentation behavior of platinum group elements in a molten glass was observed. RuO₂ and Pd metal showed similar distribution although their densities are so different, suggesting some kind of interaction between platinum group elements.
