PROCESS FOR THE CONTINUOUS PREPARATION OF PHYLLOMINERAL SYNTHETIC PARTICLES

摘要

A process for preparing phyllomineral synthetic particles formed from constituent chemical elements in stoichiometric proportions including at least one chemical element selected from the group formed from silicon and germanium, and at least one chemical element selected from the group formed from divalent metals and trivalent metals, by a continuous solvothermal treatment at a pressure above 1 MPa and at a temperature between 100° C. and 600° C., by making the reaction medium circulate continuously in a solvothermal treatment zone of a continuous reactor (15) with a residence time of the reaction medium in the solvothermal treatment zone that is suitable for continuously obtaining, at the outlet of the solvothermal treatment zone, a suspension including the phyllomineral synthetic particles.
