Abstract
Samples of silicate mineral ceramics of various compositions based on composites of granites, unconditioned apatite ores, tailings from enri chment of apatite ores, and model radioactive wastes are synthesized a nd studied. The rates at which Na+, Ca2+, Sr2+ and Cs+ leached by H2O at room temperature from the ceramics are measured. The silicate metal loceramic surpasses borosilicate glass in retention of alkali and alka line-earth metals. Several composites rival the ceramic SYNROC in reli ability of Cs immobilization.
