“…The small number of solubility means high acid resistance. The eluted ratio of phosphorus changed from 100 to 28% with the increase of cerium ratio [22]. Formation of cerium phosphate inhibited the elution of phosphate materials.…”

In this paper, we report the preparation of nickel phosphate in aqueous solution and its use as inorganic pigment. Because cerium phosphate is insoluble in acidic and basic solution, the addition of cerium was tried to improve the acid and base resistance of nickel phosphate pigment. The cerium substituted nickel phosphates were prepared from phosphoric acid, nickel nitrate, and ammonium cerium nitrate solution. The additional effects of tetravalent cerium cation were studied on the chemical composition, particle shape and size distribution, specific surface area, color, acid and base resistance of the precipitates and their thermal products

“…The optical band gap energy of thermal products at 800 decreased from 5.17 eV to 4.43 eV [20]. The color of materials changed from yellow to white (Figure 7) [21]. Figure 8 shows acid resistance of samples synthesized in various Ni/Ce ratios.…”
