| Initial Permeability Dependence on the Microstructural and Compositional Changes in Ni-Zn-Sc Ferrites (1997) | |||||||||||||||
Abstract | |||||||||||||||
| Observed variations in density, grain size and initial permeability (µic) in two series of Ni-Zn-Sc ferrites with varying concentrations of zinc and scandium have been discussed in terms of their microstructural and compositional changes. Initial amounts of scandium enhanced densification and sintering in both the series. Subsequent concentrations of only scandium caused reduction in µic in Series-I, whereas simultaneous substitutions of zinc and scandium together resulted an increase in µic in Series-II. Conclusions have been drawn towards the domination of the microstructural changes in series-I and compositional changes in series-II in the study of initial permeability. | |||||||||||||||
