“…These very low zinc phosphate contents could not provide a satisfactory anticorrosive behavior, as reported in previous work. 10,11,27,44 In previous research, it was demonstrated that zinc oxide could improve the inhibitive action of zinc phosphate. 45 In brief, the good anticorrosive performance of tested paints could be attributed to the synergism of the three compounds included in the anticorrosive mixture.…”

In this investigation, the synergism promoted by zinc hypophosphite in an anticorrosive pigment mixture is reported. This paper describes the anticorrosive behavior of a commercial pigment mixture containing zinc hypophosphite, reduced levels of zinc phosphate, and zinc oxide. The anticorrosive performance of the pigment mixture was assessed by electrochemical techniques (corrosion potential and linear polarization measurements) employing pigment suspensions. The behavior of each separate component of the mixture was also studied in the same way. The nature of the protective layer was investigated by scanning electron microscopy (SEM). In a second stage, the anticorrosive properties of the pigment were assessed by incorporating it into alkyd and epoxy paints that were evaluated by accelerated (salt spray and humidity tests) and electrochemical measurements. Experimental results showed that improved anticorrosion protection is achieved in paints with reduced zinc phosphate contents as a consequence of the synergistic interaction between zinc hypophosphite and the other components of the pigment mixture.

“…Zinc phosphate (Zn3 (PO4)2) is one of the most important multifunctional materials for potential applications, including environmentally friendly anticorrosive pigments and dental cements due to its low solubility in water/biological environment and biocompatibility. 5,6 In addition, the catalytic properties of zinc phosphate have been investigated in hydrocarbon conversion process, such as dehydration/dehydrogenation of sec-butanol and methanol conversion. 7,8 Since the first report on the synthesis of microporous zinc phosphates, 9 various techniques, including a solid-state reaction 10 and a polyol-mediated approach, 11 have been investigated for the synthesis of monodispersed and nonagglomerated zinc phosphate nanoparticles.…”

Amorphous zinc phosphate nanospheres were prepared via a sonochemical route. Zinc phosphate nanospheres were uniform in shape with an average diameter of 210 nm. The average diameter of nanospheres could be controlled by changing the pH of a precursor solution. This sonochemical method is simple, facile, economical, and environmentally benign. Non-crystalline characteristics of as-prepared zinc phosphate nanospheres were confirmed by X-ray diffraction, transmission electron microscopy, and FT-IR spectroscopy analyses. We believe this technique will be readily adopted in realizing other forms of zinc phosphate nanostructures.
