Hydroxyapatite and Hydroxyapatite-Based Ceramics
Inorganic Materials, 2002Data are summarized on the synthesis of hydroxyapatite (HA) by wet-chemical processes, solid-state reactions, and hydrothermal treatment. The conditions for HA preparation via precipitation from solutions of calcium chloride, dibasic ammonium phosphate, and aqueous ammonia are discussed at length.

Orthopedics, 1994
ABSTRACTA series of investigations over the past several years has evaluated a number of implant materials with and without plasma-sprayed hydroxyapatite (HA) coatings for use in load-bearing implant applications. HA-coated implants have exhibited greater interface shear attachment characteristics when compared to uncoated implants; these results have ...

Four coating techniques were evaluated to determine which is most suitable for producing a dense, highly adherent coating onto metallic and ceramic implant materials. Two of the selected coating methods have serious limitations for use in this particular application, and did not meet the specified criteria for satisfactory coating as defined in the ...
