Abstract
The present invention provides: a method for producing a shaped product comprising octacalcium phosphate and having a volume of 2.0 mm3 or more, comprising immersing a precursor ceramic composition containing at least one of Ca and PO4 in composition, having a solubility in H2O higher than that of octacalcium phosphate, and having a volume greater than 2.0 mm3, in a solution containing a component which is not contained in the precursor ceramic composition, among the components Ca, PO4 and H2O, which are components of octacalcium phosphate to allow the precursor ceramic composition to react, thereby converting at least a part of the precursor ceramic composition into octacalcium phosphate; and the like.

A method for producing a shaped product comprising octacalcium phosphate and having a volume of 2.0 mm3 or more, comprising immersing a precursor ceramic composition containing at least one of Ca and PO4 in composition, having a solubility in H2O higher than that of octacalcium phosphate, and having a volume greater than 2.0 mm3, in a solution containing a component which is not contained in the precursor ceramic composition, among the components Ca, PO4 and H2O, which are components of octacalcium phosphate to allow the precursor ceramic composition to react, thereby converting at least a part of the precursor ceramic composition into octacalcium phosphate.
A shaped product cured by a chemical bond of an inorganic component, or entanglement or fusion between crystals of an inorganic component, wherein the shaped product contains 10% by mass or more of octacalcium phosphate and has a volume of 2.0 mm3 or more.
