【Abstract】 The iron phosphate glass matrix is recommended to incorporate strontium waste produced from the partitioning process of Chinese HLLW. The formula of iron phosphate glasses was designed. Their structure was studied with IR spectra and their chemical durability was tested by the Product Consistency Test (PCT) method. The experimental results show that the glass matrix has good chemical durability. When the content of simulated strontium waste is within 24%(w/w) to 28%(w/w), that of Fe 2O 3 is above 24%(w/w) and the molar ratio of O/P is 3.5 to 3.6 in the composite, the glass matrix has the best chemical durability.
