In this study, we investigated a preparation method for compositionally graded spherical particles in which a solution containing hydroxyapatite(which has with low solubility) and potassium nitrate(which has high solubility) was spray-dried to obtain the particles. In this process, potassium nitrate was filled up internally. Furthermore, we confirmed that these compositionally graded particles released the internal inclusion material in water in a controlled manner. However, we were unable to establish a clear superiority in a cultivation examination. This could be attributed to the low mechanical strength of the particles ; therefore, we suggest that it was effective in improving the strength of the particles.

在这项研究中，我们研究了一种合成梯度球形颗粒的制备方法，其中含有羟基磷灰石（溶解度低）和硝酸钾（溶解度高）的溶液喷雾干燥得到颗粒。在这个过程中，硝酸钾被内部填充。此外，我们证实了这些成分分级颗粒在水中以受控的方式释放了内部包裹体材料。然而，我们无法在培养考试中确立明显的优势。这可能是由于颗粒的机械强度低；因此，我们认为它对提高颗粒的强度是有效的。
