摘要: Powders and divided solid materials are widely represented as finished or intermediary products in industries varied foodstuffs, cosmetics, construction, pharmaceuticals, electronic transmission, energy. Their optimal use requires a mastery of the transformation process based on knowledge different phenomena concerned (sintering, chemical reactivity, purity, etc.). modelling understanding need prior acquisition sets data characteristics which more less challenging to obtain. The goal this study is present physico-chemical characterization techniques adapted uranium-containing powders analyzed either raw state after specific preparation (ionic polishing). new developments touched concern dimensional for grains pores by image analysis, surface powder reactivity characterization. examples discussed from fabrication used nuclear fuel cycle.
