Production of Nanoparticles of Hydroxyapatite by Using a Rotating Disk Reactor

摘要

This paper deals with the feasibility to produce, in a continuous mode, nanoparticles ofrnhydroxyapatite (HAP) by means of a rotating disk reactor. This device is capable tornestablish the required conditions of micromixing in correspondence of the reagentsrnfeeding point. The experimental work consists mainly of investigating the effect of thernfeed location of the reagents over the rotating disk surface. It was observed a greatrninfluence of the feed location on the particle size distribution of the produced HAP, onlyrnthe best feed location allow the production of particles smaller than 100 nanometers.rnThe obtained experimental results were interpreted on the light of a simplifiedrnsimulation model. The model provided the map of the specific dispersed energy, thusrnallowing identifying the zones of the disk where micromixing may occur.
