The present invention provides a method for the processing of particles of metal phosphates or particles of mixed metal phosphates and in particular lithiated metal phosphates and mixed metal phosphates. The processing occurs, for example using a mechanofusion system as depicted in Figures 1 and 2. In general, the powder materials are placed in a rotary container and are subjected to centrifugal force and securely pressed against the wall of the container.
