Abstract

Abstract

This paper investigated the influencing factors on the leakage behavior of strontium titanate form SrTiO₃a. The leaching rate was evaluated by the materials characterization center method. Experimental results showed that the leaching rate of SrTiO₃a gradually decreased with time and was less than 0.1 g·m^-2·d^-1, twice orders less than that of glass solid. It was found that SrTiO₃a had a steady chemical property and was a good form for high lever radioactive-wastes.
