A hydroxyapatite slurry was prepared by stirring into water a stoichiometric mixture of
tricalcium phosphate and calcium hydroxide until the solid content was 50 wt%. Samples …

A potassium-doped synthetic apatite was prepared by soaking hydroxyapatite in potassium
carbonate and potassium chloride solutions. The hydroxyapatite was prepared by firing slip …

Calcium hydroxyapatite has been prepared due to a direct precipitation reaction between
0.3 m orthophosphoric acid solution and 0.1 mol calcium hydroxide dispersed in 200 ml …

Calcium hydroxyapatite powders were prepared by hydrothermal reactions of calcium
pyrophosphate and calcium oxide. Primary particles of the hydroxyapatite obtained were …

Hydroxyapatite as well as tricalcium phosphate is known to be biocompatible with human
bone and tooth. Advances in biomaterials are occurring at an accelerated rate and much …

This chapter describes the structure and composition of synthetic hydroxyapatite. It
discusses the deviations from the ideal structure as a result of ionic substitutions. Studies of …

Poorly crystalline, apatitic calcium phosphate powders have been synthesized by slowly
adding a Na-and K-containing reference phosphate solution with a pH value of 7.4 to an …

Hydroxyapatite powders were prepared by calcining freeze-dried mixtures of calcium
acetate and tri-ethyl phosphate, in which no calcium phosphate was formed. Results of X-ray …

In this paper a pure calcium hydroxyapatite prepared from aqueous solutions at low
temperature, was analysed by a large number of techniques in six Institutes. The techniques …

Carbonate containing hydroxyapatites were prepared hydrothermally between 2000 and
20,000 psi and 250 and 900° C using H 2 O or CO 2 pressure. On the basis of IR, x-ray and …
