cze Comparison of the Anticorrosion Efficiencies of Pigments Based on Condensed Phosphates and Polyphosphosilicates The paper deals with studying the anticorrosive properties of condensed phosphates and polyphospahates in the coatings. The pigments contain in the most cases as aluminium in a combination with zinc, stroncium, calcium or a combination with all the cations. The investigated anticorrosive pigments differ in water solubility, inhibition efficiencies of their aqueous extracts and also the efficiencies in the coatings protecting steel substrate to corrosion. Two types of condensed anticorrosive pigments were compared. The anticorrosion properties of polyphosphosilicates are inferior to those of polyphosphates. The high anticorrosion efficiency was found at a comparative pigment, represented by zinc phoshosilicate. N
