Embodiment 1
[0028] A micron hexagonal column strontium hydroxyapatite, its synthesis process comprises the following steps:
[0029] 1) Add 0.0058 mol of strontium nitrate and 0.0035 mol of sodium dihydrogen phosphate in sequence in a beaker with 100 ml of distilled water, and stir to obtain a mixed solution;
[0030] 2) Add 0.6667 mol of urea to the mixed solution, react for 20 hours under the condition of stirring, and the temperature of the water bath is 95°C, and then stand and age for 24 hours at room temperature, the solution is separated, the upper layer is clear liquid, and the lower layer Precipitation of micron hexagonal strontium hydroxyapatite;
[0031] 3) Naturally cool to room temperature after the reaction is finished, place the precipitated product in a beaker, wash the precipitate alternately with absolute ethanol and deionized water, until the air bubbles are generated during suction filtration; then filter the obtained powder filter cake, Dry at 100°C for 24 hours with...
