This study characterizes major bismuth and phosphate-bearing phases in Hanford radioactive waste from the bismuth phosphate process using scanning electron microscopy with energy dispersive spectroscopy. Large bismuth phases displayed lath morphology and consisted of sodium, iron, bismuth, and phosphorus. The majority of the bismuth and phosphate observed was in small particulate (< 2 A mu m in diameter) containing sodium, phosphorus, iron, and nickel. Additionally, phosphorus was included in a sodium-aluminum-phosphate lath-shaped species. Characterization of these waste types is of particular importance since they may have the bounding particle properties for designing waste mixing and transport processes used during treatment.
