Preparation of ultrafine Lio.43Zno.195Fe2.3704 Lithium Ferrite powder

Ceramics preparation strongly depend on the features of the starting materials, morphology, particle size distribution, homogenate, and nature of defects. This is particularly true for lithium-based ferrites used for microwave and magnetic applications. One of the most effe tive means the powder synthesis process itself. Freeze drying has found application in the production of nanoparticles for electTochemical, environmental, engineered materials, and pharmaceutical industries. The retention of the homogenous properties typically found in a solution, the small size of particles produced, are the primary reasons for choosing freeze drying. Thus, the present work deals with the preparation by freeze drying of ultra fine particles ofLi0.43Zno.195Fe2.370 4 compound.
