Effect of raw material and process conditions on properties of Mn-Zn ferrous ferrites

Studies have been carried out on samples of manganese zinc ferrous ferrites prepared using different types of raw materials and varying process conditions like mixing, calcination, and sintering under controlled atmosphere in production type tunnel kilns. Results are presented to show that by optimization of process conditions it is possible to prepare the following. a) Grade-I ferrites with high purity materials, though processed in different ways. b) Grade-II ferrites can tolerate Silica of 0.5% to 0.6% which is normally found in beneficiated iron ore.
