THE DETERMINATION OF SILICON IN URANIUM DIOXIDE

Technical Report ·
OSTI ID:4226305
;
The sample is dissolved in nitric/hydrochloric acid nnixture. Any insoluble matter is fused with sodium carbonate, and the solution from the melt is added to the main solution. The silicon is determined absorptiometrically by the formation of the reduced silicomolybdic acid complex. The method is suitable for silicon contents of 20 to 1000 ppm. The error except in the lowest range should not exceed plus or minus 5%. (auth)
