  • Process for preparation of hydroxyapatite coatings
    Patent number: 6280789
    Abstract: Coatings of scarcely crystalline carbonated hydroxyapatite are deposited on metallic or ceramic substrates, by immersing the substrates in a solution containing calcium phosphate and bicarbonate ions, with a molar ratio calcium/phosphate from 0.8 to 2 and a pH from 6.8 to 8.0. Subsequently, the solution is heated to 50-80° C., thus raising the pH and causing a spontaneous deposition of carbonated hydroxyapatite on the substrates. The obtained coatings are highly biocompatible, osteoconductive, bioactive and biodegradable, and can be utilized in structures used for preparing orthopaedic and dental prostheses and implants.
