Abstract
The present invention relates to a method for producing whitlockite, and whitlockite produced thereby. A method for producing whitlockite according to one embodiment of the present invention comprises: a step of preparing a precursor solution by mixing a first solution containing a calcium (Ca) ion source material, a second solution containing a magnesium (Mg) ion source material, and a third solution containing a phosphate (PO4) source material; a heat-treatment step of heat-treating the precursor solution; and a step of separating and purifying the precipitate formed in the solution, after the heat-treatment step.
Claims4
A method for producing whitlockite comprising:
- (a) preparing a mixed solution by mixing a first solution containing calcium chloride with a second solution containing magnesium chloride;
- (b) preparing a precursor solution by adding the mixed solution dropwise to a third solution containing sodium hydrogen phosphate in a reactor configured to have such a size that whitlockite is obtained in kilogram scale;
- (c) heat-treating the precursor solution at 50° C. to 90° C. for 12 hours to 24 hours;
- and
- (d) separating and purifying a precipitate formed in the precursor solution after the heat-treatment step.
