Modelling breakage and reagglomeration during fine dry grinding in ball

With the increase in ball-milling time, the surface area of Zr(OH)4 powders decreased from 272.6 m2/g to 112.9 m2/g (Table S1), which is attributed to strong interparticle agglomeration caused by ball-milling treatment (Fig. 2(d1 −d4)). A similar phenomenon was also observed by Cedeño-Mattei et al. [20] and Fadda et al. [21].Similar results regarding N-doping of graphene were reported in the literature by Xue et al. for graphite milled in presence of melamine at the ratio graphite/melamine of 1:10 for a duration of 48 hours in a planetary ball mill .
