Effect of Particle Size on Maximum Energy Product of Wastederived Ferrites

Ferrite is an important component for electric motors, loud-speakers, EMI suppressors and transformer core. Hematite (Fe2O3) and strontium carbonate are commonly used to prepare ferrite. In this work, waste-derived hematite powder was milled using ball mill, high-energy milling and high-energy blend...
