Abstract
Abstract—A new method for obtaining the nanoscale hydroxyapatite with low crystallinity from aqueous solution of calcium malate Ca(C4H5O5)2 and ammonium hydrophosphate (NH4)2HPO4 at room temperature, molar ratio Ca/P = 1.67, and pH 9 was proposed. After synthesis and drying, the sample was a transparent composite with a matrix from the by-product of the reaction of organic nature containing nanoscale particles of calcium phosphate. The phase composition of the sample after thermal treatment at 900°C was represented by calcium hydroxyapatite.
