摘要：NOVELTY - A strontium phosphate-based nano-assembly spherical pigment has diameter of 2-3 mu m and thickness of 20-30 nm. USE - Strontium phosphate-based nano-assembly spherical pigment. ADVANTAGE - The strontium phosphate-based nano-assembly spherical pigment has excellent dispersibility, biocompatibility and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of strontium phosphate-based nano-assembly spherical pigment, which involves adding strontium nitrate solution and sodium phosphate solution to a beaker, then adding benzotriazole and 0.05-2 %mass surfactant, stirring and reacting, washing the precipitate with deionized water and drying at 60-95 degrees C, where the weight ratio of strontium nitrate and sodium phosphate is 3:2, and the surfactant is polyethylene glycol, Triton x-100 (RTM: Nonionic surfactant), hexadecyltrimethylammonium bromide or Tween 80 (RTM: Polysorbate 80).
