| Abstract: | | 1. |
It has been determined experimentally that for a given level of power input, the limiting surface area Smax achieved in size-reduction increases, and the rate constant for the size-reduction of metal halide crystals decreases with increasing bond energy of the crystal lattice in the order KCl < nacl="">< naf="">< lif.=""> | | 2. |
A parameter is proposed for describing the size-reduction of metal halides both in the step in which destruction is overcome, and in the process in which dynamic equilibrium is established between the processes of particle dispersion and aggregation.
| | 3. |
Relationships have been obtained that make it possible to calculate precisely Smax for any metal halide with the NaCl structure by using the Smax value of any other metal halide regardless of its defect structure.
