Resumo
To guarantee the reliability and comparability of analytical data, the use of reference materials is essential.
Uranium intermetallic compounds, in particular U3Si2, have been the preferred fuel materials for high flux research
reactors. A method for the quantitative determination of the minimum representative sample mass of a candidate
for reference material for determination of total uranium and silicide is described and illustrated in this paper. The
analytical method used for determination of total uranium was the high precision potentiometric titration method
of Davies and Gray, while total silicide was determined gravimetrically. The study was conducted according to
ISO Guide 35. A preliminary test for homogeneity can be performed after homogenization as an integral part of
the candidate reference material preparation.
