Abstract: Process of press-granulating non-ductile salts and salt mixtures, such as kieserite (MgSO4.H2O), langbeinite (K2SO4.2MgSO4), polyhalide (K2SO4.MgSO42CaSO4.2H2O), arcanite (K2SO4) and anhydrite (CaSO4) for preparing stable, storable granulate, by pressing a mixture of fine grains of salt and a viscous, sugar-containing additive, such as molasses having a total sugar content in the dry matter of from 47 to 55%, by roller pressing at pressures up to 260 bar. The press scraps initially obtained, which are ductile, are solidified by maturing of the material at temperatures between 20 and 40° C. and maturing times of 3 to 8 hours prior to crushing them in impact mills and sieving.

Abstract: A mixed nickel hydroxide cathode material for use in alkaline storage batteries and having a bimodal particle size distribution includes a main population of particles and a secondary population of particles. The main population has a median mass-based particle size distribution value, derived from laser particle analyses, of between 5 ?m and 25 ?m. The secondary population has a median mass-based particle size distribution value, derived from laser particle analyses, of between 0.3 ?m and 3 ?m. The main population is present in the mixed nickel hydroxide cathode material in a proportion of between 70% and 96% by mass.
