A study of hydroxyapatite fibers prepared via sol–gel route
2004
Abstract Hydroxyapatite (HAP) fibers were prepared by spinning sols prepared from a 2-butanol solution of phosphorous pentoxide and calcium acetate solution in distill water. Lactic acid was added as a spinning aid. The Ca/P ratio was maintained at 1.67. The fibers obtained were dried and calcined at different temperatures up to 1000 °C. X-ray diffraction studies showed the presence of pure HAP phases up to a calcinations temperature of 1000 °C. The fibers showed the presence of the FTIR signature peaks of HAP and had uniform diameter and dense microstructure.
