Environmentally safe pigments based on synthetic zeolite and monophosphates of zinc, calcium, and manganese were obtained by mechanochemical synthesis. Optimal conditions for their dispersion were determined. Scanning electron microscopy and energy dispersive analysis were used to evaluate the surface morphology and determine the elemental composition of the obtained pigment, which indicate the intercalation of phosphorus and relevant metals into the zeolite structure. Desorption of phosphate anions in a 0.1% NaCl solution was found to increase in the series Na-A/Zn (H 2 PO 4) 2 - Na-A/Ca(H 2 PO 4) 2 - Na-A/Mn(H 2 PO 4) 2 , and the maxima of their concentrations for all the compositions were detected after 48 h of holding. The concentration of desorbed phosphate anions in the studied environment during mechanochemical synthesis is approx. 2.0 times higher than that during ion-exchange synthesis. The obtained results indicate the effectiveness of the mechanochemically obtained pigment based on zinc monophosphate and zeolite as part of paint coatings for the protection of structures made of aluminum alloys.
