| Popis: | Nuclear waste can be vitrified by mixing it with glass-forming and -modifying additives. The resulting feed is charged into an electric glass melter. To comprehend melting behavior of a high-alumina melter feed, we monitored the volume expansion of pellets in response to heating at different heating rates. The feeds were prepared with different particle sizes of quartz (the major additive component) and with varied silica-to-fluxes ratio to investigate the glass melt viscosity effects. Also, we used additional melter feeds with additives premelted into glass frit. The volume of pellets was nearly constant at temperatures |
