Abstract
A process for producing hydroxyapatite fibers is disclosed. The process comprises the steps of preparing a mixture of (1) calcium metaphosphate fibers and (2) calcium oxide, calcium hydroxide and/or calcium carbonate powder; heating the mixture to convert the calcium metaphosphate to hydroxyapatite; and removing calcium oxide in the heat-treated mixture by dissolving off from the resulting mixture.
