Definitions
- the particle size of the aluminum load (recall here that different unimodal particle size distribution of aluminum fillers may also occur (see examples below)) is a parameter of the second order, with reference to technical problems cited above .
- the aluminum particles therefore have a median diameter less than or equal to 40 microns.
- the best results, up to the production of alumina monomodal particle size centered at 1 to 3 microns, are obtained with aluminum particles with a median diameter of between 1 and 10 microns and certain combinations of ammonium perchlorate class A and B (see examples below) introduced into the mixer to form the ammonium perchlorate feedstock.
