  • Hydroxyapatite, composite, processes for producing these, and use of these
    Patent number: 6395037
    Abstract: A hydroxyapatite consisting substantially of Ca10(PO4)6(OH)2, and having a crystal structure which has at least two diffraction peaks at 31-32 degrees and 26 degrees in X-ray diffractometry; and a process for producing a hydroxyapatite which comprises the step (A) of immersing a substrate in a first aqueous solution containing calcium ions and a second solution containing PO4 ions to generate the hydroxyapatite at least on the surface of the substrate and the step (B) of recovering the hydroxyapatite from the substrate.
    Type: Grant

  • Method for preparing hydroxyapatite composite and biocompatible material
    Patent number: 6387414
    Abstract: A method for preparing a hydroxyapatite composite is disclosed. This method comprises alternately soaking a matrix which has been made hydrophilic at least on its surface, in a calcium ion aqueous solution containing calcium ions and substantially free of phosphate ions and in a phosphate ion aqueous solution containing phosphate ions and substantially free of calcium ions to securely form hydroxyapatite at least on the surface of the matrix. Also disclosed is a biocompatible material composed of the hydroxyapatite composite obtained by the method.
