摘要

PURPOSE: A preparation method of calcium phosphate ion solutions, calcium phosphate colloid ion solutions formed by maintaining the calcium phosphate ion solutions at low temperature, dots or thin films of calcium phosphate formed on a solid substrate using the calcium phosphate colloid ion solutions, and calcium phosphate granules prepared in the calcium phosphate colloid ion solutions are provided. CONSTITUTION: The preparation method of calcium phosphate ion solutions comprises a step (i) of preparing an ion solution having pH of 6.0 to 10.0 including phosphoric acid ions; a step (ii) of preparing an ion solution having pH of 6.0 to 10.0 including calcium ions; and a step (iii) of preparing calcium phosphate solution having pH of 6.0 to 10.0 by mixing the ion solutions. The preparation method of calcium phosphate ion solutions comprises a step (i) of preparing an ion solution having pH of 6.0 or less including phosphoric acid ions and calcium ions; and a step (ii) of preparing calcium phosphate solution having pH of 6.0 to 10.0 by mixing a basic solution with the ion solution. The material including dots is characterized in that it is formed by a method of comprising a step (i) of preparing calcium phosphate ion solution prepared by a preparation method comprising a process (a) of preparing calcium ion and phosphoric acid ion solutions by dissolving calcium salt and phosphoric acid salt into an acidic solution, a process (b) of mixing the prepared calcium ion and phosphoric acid ion solutions with an alkali solution at low temperature, and a process (c) of removing amorphous calcium phosphate granules or crystals from the prepared solution; a step (ii) of preparing calcium phosphate colloid ion solution in the calcium phosphate ion solution by leaving alone the prepared calcium phosphate ion solution at a temperature of 0 to 60 deg.C; and a step (iii) of pouring the prepared calcium phosphate colloid ion solution onto a solid substrate.
