The obtained UzOg powder is suitable to be used as a nuclear fuel. It could be checked by analyzing its physical and chemical properties and those ones resulting from the obtained fuel plates. Metallographic tests were carried out in those fuel plates in order to determine the UzOg particle size distribution by image analysis. The main conclusions show the applicability of the method, owing to the similar powder and fuel plates properties, as compared to the conventional method.32-37openAccessuranium oxides u3o8powdersfuel elementsfuel platesauccalcinationsinteringparticle sizeArtigo de periódico189/19110.4028/www.scientific.net/KEM.189-191.32https://orcid.org/0000-0002-2147-8295
