Processes for treating coral and coating an object

摘要

The present invention generally relates to an improved process for the hydrothermal conversion of coral into hydroxyapatite, a process for coating an object with hydroxyapatite, a process for coating an object with a divalent metal phosphate and uses of objects prepared by these processes. Following the processes according to the present invention, the resultant hydroxyapatite has greater strength and bioactivity than that of the coral to its conversion.
