Abstract:
1. A method for producing bioactive composites comprising: (1) a step of immersing a porous substrate in a solution containing at least calcium ions and hydrogenphosphate ions, thereby distributing the solution to the inside of at least a part of the pores of the substrate, and then (2) a step of elevating the temperature of the solution by 20° C. or more and/or increasing the pH value of the solution from a pH value in the range of 4.0 to 7.1, to a pH value in the range of 7.2 to 9.0, thereby depositing particles of particle size 1 nm to 500 μm containing a calcium phosphate compound as the major component inside the pores into which the solution is introduced.
