<BR>Solid forms fixing nuclides were produced from Cs-mordenite and Sr-zeolite A by calcination at 1, 200°C for 1 h. Cesium and strontium were uniformly dispersed in pollucite (CsAlSi2O6) and Sr-feldspar (SrAl2Si2O8), respectively. Compressive strength of the products increased with decreasing particle size of starting zeolites, yielding the value above 1.2 GPa for the Cs product. Thermal conductivities of Cs and Sr products were measured to be about 1.0 and 0.6 W/(m•K), respectively. Leachability of Cs was in the order, 0.1 M HNO3>0.1 M NaOH>0.1 MNaCl>deionized water. The Sr product had lower leach rate compared with the Cs product, and no Sr was detected in deionized water up to 90°C
