Mechanochemical synthesis of hydroxyapatite from

Dry grinding of Ca(OH)2-P2O5 and CaO-Ca(OH)2-P2O5 mixtures was conducted by a planetary ball mill to investigate the mechanochemical solid-phase reaction for the synthesis of hydroxyapatite (Ca10(PO4)6(OH)2, HAp). HAp was synthesized by grinding of the two sets of mixtures. The formation of HAp from the Ca(OH)2-P2O5 mixture was more advantageous

Effect of Mechanical Activation on the Morphology and

We have studied the effect of grinding in planetary mills on the phase composition, morphology, and water content of hydroxyapatite powder. The results indicate that milling for even relatively

2012-3-1  Grinding of HA is therefore more suitable to achieve highly defined patterns with smooth surfaces. If an application requires rougher channel surfaces, milling of HA is the better choice. Similar to the finding for hydroxyapatite, the SEM micrographs of the ground zirconia samples show a smoother surface structure as compared to the milled ones.

Effect of mechanical activation on the morphology and

2010-12-23  We have studied the effect of grinding in planetary mills on the phase composition, morphology, and water content of hydroxyapatite powder. The results indicate that milling for even relatively short times, which reduces the average particle size by a factor of 2, causes the monetite present in the unmilled powder to disappear and reduces the crystallite size of the

The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2 (or 1:-2.5 or 1:-3). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.
