Influential factors on morphology of hydroxyapatite crystals

Abstract

Needle-like hydroxyapatite crystals were synthesized by homogeneous precipitation method with water-soluble calcium salts and phosphates. The work focuses on the analysis of influencing factors on length and lengh/diameter ratio of hydroxyapatite crystals, which are main characteristics of reinforcement materials. The effects caused by system temperature, concentration of nutrient, and additives are discussed, and the optimum reacting condition is given.

Keywords
