Two main research axes were defined for this Ph-D work : (i) studying the effect of light elements (B, C) on the stability of U-Si compounds, and (ii) identifying and physically characterizing new phases in the U-Pt-Si system. Minor additions of carbon and boron in U-Si samples revealed that the formation of U₅Si₄ would be correlated to the presence of these light elements, questioning its existence in the U-Si system. To evaluate the boron potential as a stimulant for non-metallic light elements of the second period (C, N, O), the isothermal section of the ternary phase diagram U-Si-B has been drawn at 927 °C, disclosing solid equilibrium mainly between the U-B and U-Si binary axes and the existence of the novel compound U₂₀Si₁₆B₃, isostru...
