Porter, J A

Two procedures were developed for the quantitative precipitation of neptunium(IV) oxalate that filters rapidly and is readily calcined to the oxide. In the preferred procedure the oxalate was precipitated at elevated temperature from solutions of low acidity. In the alternative procedure the oxalate was precipitated at room temperature from solutions of higher acidity. Neptunium oxide was prepared by calcining the oxalate at 500$sup 0$C in a flowing stream of air or nitrogen. (auth)
