Abstract

The samples from A-type zeolite and ground soda-lime glass powders were solidifed by calcinations at 600 to 800°C in air atmosphere. These hybrid zeolite/glass samples at 700°C were in part insufficiently densified and hybrid samples were fully densified at 800°C, although the densification was not generated at 600°C. A-zeolites were still stable in glass melt at 800°C for hybrid zeolite/glass samples. These hybrid zeolite/glass samples had the ion exchange ability of 20% against Sr²⁺ and the high ability over 80% against Cs⁺ as well as A-zeolite. Microstructures of obtained hybrid zeolite/glass samples were evaluated.
