MECHANOCHEMISTRY: A NEW ROUTE FOR THE PREPARATION OF CARBONATEAPATITE

The aim of the current work is to present a new route to synthesise carbonateapatite with low cristallinity and carbonate content in the range of biological apatites. Mechanical milling has been employed for this preparation and the influence of the different conditions on the final material characteristics has been studied. A higher time of grinding is required under a CO₂ atmosphere (210 hours) than under air (135 hours). However, in the sample obtained in air, some of the starting CaCO₃ still remains.
