... reagent, wax (or paraffin) as the solvent, and oleic acid as the surface active agent, were selected along with bioactive materials such as β-TCP ceramic powder as the main component. The selected components were mixed into a slurry at 30–120°C and shaped into a green body with a hot die-casting machine...

...Robert B. Heimann Abstract In modern orthopedics, plasma-sprayed hydroxylapatite coatings are applied routinely to metallic parts of hip and knee prostheses, as well as to dental root implants to render them osseoconductive, that is, able to assist the body in creating new bone by ingrowth of bone...

... Elliott's review, 1998 ). A-type substitutions are observed only in biological apatite or in hydroxyl-apatite synthesized in particular conditions, while B-type represents the most natural carbonated apatites. Polarized infrared spectroscopy of human dental enamel shows that CO 3 probably occupies two...
