The behavior of ruthenium oxide (RuO2) in aluminoborosilicate glass used for the stabilization of nuclear waste was investigated. It was found that 0.025 mass% RuO2 dissolved as Ru4+ in the glass at 1400degreesC, which caused the glass to turn yellow. When the RuO2 amount was 0.05 mass%, needle-shaped crystals formed in the glass during slow cooling. If the added amount exceeded 0.1 mass% and the cooling rate was slow, it separated rapidly and the glass became pale after cooling. No dissolution of ruthenium was detectable after melting at 1200degreesC.
