To prepare the bulk samples for degradation testing, the powder was finely spread across 10mm filter paper to enable uniform degradation across the sample and increase kinetics. Each different compound was plated in triplicate to ensure enough yield for post-degradation powder X-ray diffraction. Once loaded in the chamber, samples were held at 0.15±0.01 Sol, under 85±2℃ sample tray temperature, and 85±5% air humidity for ~150 hours. Samples in the chamber were imaged every minute. After the degradation testing concluded, the samples were removed from the chamber and post powder X-ray diffraction measurements were taken.
