Влияние условий механического измельчения на дисперсность порошка литиевого феррита

Abstract

In this paper, the effect of mechanical milling in a planetary ball mills on dispersity of the synthesized lithium ferrite powder was investigated by laser diffraction technique. The mechanical milling of powder was carried out by two planetary ball mills: SPEX 8000М and Fritsch Pulverisette 5 for different times. The results showed that an increase in milling time leads to a slight decrease in the average particle size of the ferrite powder in case of using of both ball mills. However, only milling in a SPEX planetary mill leads to a higher homogeneity of the ferrite powder, while the milling in Fritsch causes the intensive processes of particle aggregation.
