Preparation and structural investigations of titanium substituted Li-Zn ferriets

ABSTRACT

The mixed ferrites Li0.35 Zn0.30 Tix Fe2.35-x O4 [where x 0.0 to 1.0] were prepared using standard ceramic methods and were sintered at 1150 in static air atmosphere. The formation of ferrite spinel structure was investigated using X-ray diffraction and IR techniques. It was found, that samples with Ti content [x <0.2] have a spinel cubic structure. With increasing titanium content, bulk density and diameter shrinkage were found to decrease, while apparent porosity and grain size increased. Samples with x >0.2 were found to have more than one structural phase
