We have performed an elemental abundance analysis for Sirius, Vega, and three peculiar silicon stars: HD 43819, HD 192913 and HD 133029 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.

Key words: stars: abundances -- stars: chemically peculiar
