A modified glass-bonded sodalite ceramic waste (CWF) form approach was used to fabricate ACWF-NaI or ACWF-AgI iodosodalite [i.e., Na8(AlSiO4)6I2] waste forms by occluding either NaI or AgI, respectively, into zeolite 4A at elevated temperatures, adding an NBS-4 glass binder, and firing at 925°C. The phase purity of ACWF-NaI was 82.6 mass% Na8(AlSiO4)6I2 (with amorphous remainder) while the ACWF-AgI only had 25.9 mass% Na8(AlSiO4)6I2, despite the iodine being added as AgI; the remainder phases for ACWF-AgI included NaAlSiO4 (15.1 mass%), AgI (4.5 mass%), and Ag0 (0.2 mass%). This study shows that, starting from two different iodine salts, that the CWF process could be used for immobilization.
