Abstract
The present disclosure relates to an apparatus for fluidised-bed chemical vapour deposition from a gaseous phase allowing the temperature of the fluidised bed to be stabilised during the deposition and also to an associated method for its implementation, the apparatus being characterised in that it comprises a porous thermal insulator present in an inlet zone and configured to be passed through by the gaseous phase, said porous thermal insulator having an effective thermal conductivity at 20° C. less than or equal to 3.5 W·m-1·K-1.
