The method for synthesizing nano zinc phosphate includes the following steps: under the condition of 15-150 deg.C and normal pressure mixing zinc salt powder, inorganic phosphate powder and template agent according to a certain proportion, grinding for 10-180 min., heat-insulating and standing still, then using water to wash out the soluble inorganic salt side product in the reactant mixture, filtering, drying and pulverizing so as to obtain nano-grade zinc phosphate crystal with mesoscopic micropore structure. |
