Carbonate apatite form that has three-dimensional fully interconnected pore was prepared based on so-called ceramics form preparation method. First, α-tricalcium phosphate (α-TCP) form was prepared by immersing polyurethane form into α-TCP powder suspension. The form was heated in an electronic furnace for sintering α-TCP as well as for burning out of the polyurethane form. Then hydrothermal treatment was preformed at 200 degrees in the presence of saturated sodium bicarbonate for 24 hours. Although the mechanical strength of the carbonate apatite form was poorer when compared with α-TCP form, we found that the hydrothermal treatment of α -TCP form result in the formation of B-type carbonate apatite form without changing the ideal morphology of α -TCP form.
