Iron phosphate glass waste forms for vitrifying Hanford AZ102 low activity waste (LAW), part I: Glass formation model

A glass formation-composition model that formalized the above findings was developed using the Classification and Regression Tree (CART) analyses. The CART model was validated by testing the glass formation characteristics of several additional compositions whose (O/Na) molar ratio was maintained ≤ 4.35, i.e., the compositions were expected to form glass. This model is expected to identify similar molar ratios for predicting glass formation/crystallization of iron phosphate based compositions containing not only other Hanford LAW streams, but high level wastes as well. Using the compositions that formed glass, property-composition statistical models for the waste forms were also developed and will be reported in a second paper.
