A choosing of the disperse sample for investigation of magnetic properties of the disperse phase particles. Noticing of volume fraction limiting

Abstract

The paper provides a thorough analysis of existing and obtained experimental dependences of magnetic susceptibility of the disperse samples containing a disperse phase of magnetite particles on the concentration of this phase. We proved a possibility of obtaining the information on the particles magnetic susceptibility using the data of the initial section (nearly linear) of such dependence at the range of volume fraction up to 0.2. We considered a possibility of accuracy increase of such information for narrowed range of volume fraction (it is up to 0.02–0.05 that is usually recommended). At this range concentration dependences follow a self-consistent linear trend.
