Thermal Substrate Deposition Hydroprocessing

This deposition method is based on the fact that the solubility of hydroxyapatite decreases with increasing temperature. The dependence of the solubility product of hydroxyapatite on the temperature is given by the equation (Kuroda et al., 2002a, 2002b Kuroda and Okido, 2012) 

Despite these promising results, there is an urgent need to improve the homogeneity, density, and, in particular adhesion of the calcium phosphate layers formed by the thermal substrate (hydroprocessing) method.
