Resumen:
Abstract. We have performed an elemental abundance analysis for Sirius, Vega, and three peculiar silicon stars: HD43819, HD192913 and HD133029 using Blackwell diagrams and observational data taken from the literature. We have compared our results with previous abundance and microturbulence velocity determinations to check the validity of Blackwell diagrams applied to CP stars. We found a very good agreement.
