Percolation in radioactive-waste glass melt with RuO

Ogawa, Toru

Molten glass containing RuO particles develops electronic conduction, which causes unstable operation of the joule-heated melter for the radioactive waste vitrification. Percolation behavior of molten glass-ruthenium oxide composites was examined by noting hierarchical formation process with four length scales. A low percolation threshold less than 1 vol% was reasonably reproduced by assuming the packing of soft RuO rods in the primary aggregate, and applying Bruggeman's effective medium approximation for the higher aggregates and their clusters.
