摘要: Abstract The amorphous calcium phosphates were synthesized by the precipitation from non-toxic D -gluconate precursor solutions. low number of nanosized well-ordered deficient hydroxyapatite clusters separated with phosphate matrix was found at short aging times. content intramolecular water in aggregates decreased an amount and maturation time. majority α-tricalcium phase formed after annealing samples a high volume fraction nanocrystalline apatite-like respectively. very fine intermediate during thermal transformation to final β-tricalcium phosphate. rise disaggregation coarse particles smaller time verified. different size responsible for formation various phases treatment.
