THE GRAVIMETRIC DETERMINATION OF NIOBIUM IN URANIUM-NIOBIUM ALLOYS

Technical Report ·
OSTI ID:4242655
The bulk of the Nb is precipitated from a sulfate solution of the alloy by hydrolysis. The remainder is precipitated by tanamic acid and cinchonine. The precipitate is then ignited and weighed as Nb/sub 2/O/sub 5/. The method is suitable for alloys containing 0.2 to 0.4% Nb. Tungsten interferes. (T.R.H.)
