THE DURABILITY OF SOME SILICATE GLASSES THAT COULD BE USED IN FISSION PRODUCT DISPOSAL

Technical Report ·
OSTI ID:4249872
The corrosion by water of glass made by fusing nepheline syenite with various fluxing agents has been investigated. The objective is to obtain a workable glass that would incorporate waste fission products and have a high resistance to attack by water. Glass of composition 15 wt.% CaO, 85 wt.% nepheline syenite, has been found to have a corrosion rate of 2 x 10/sup -8/ g glass/cm/sup 2/day at room temperature after the first few days of water contact. The effect of pH on the corrosion rate has been investigated and also the selective leaching of cations of different valency. (auth)
