| Research Abstract |
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.
