Influence of CoFe2O4 particle size on the development of in-situ phases and magnetic properties of ex-situ combustion derived ferrite-BaTiO3 composite
The evolved in-situ phases may tune the structural parameters and magnetic properties of the ferrite-BaTiO3 based composite. Here, CoFe2O4 is prepared, and its particle size is modified by calcination temperature. Further, it investigates the influence of CoFe2O4 particle size on the development of in-situ phases in ferrite-BaTiO3 based composite prepared via an ex-situ gel- combustion and studies its structural parameters as well as magnetic properties at different calcination temperatures. In-situ phases such as plate-like morphologies of barium hexaferrite and hexagonal barium titanate are evolved along with polyhedral barium titanate and cobalt ferrite in these composites, but the development of these in-situ phases is found to be dependent on the particle size of CoFe2O4 as well as calcination temperature of the composite powders. Structural parameters, crystallite size, particle size, weight% of phases, and M-H loop as a function of the calcination temperature of these composites have been studied in detail.
期刊介绍：
While ceramics have traditionally been admired for their mechanical, chemical and thermal stability, their unique electrical, optical and magnetic properties have become of increasing importance in many key technologies including communications, energy conversion and storage, electronics and automation. Electroceramics benefit greatly from their versatility in properties including:
-insulating to metallic and fast ion conductivity
-piezo-, ferro-, and pyro-electricity
-electro- and nonlinear optical properties
-feromagnetism.
When combined with thermal, mechanical, and chemical stability, these properties often render them the materials of choice.
The Journal of Electroceramics is dedicated to providing a forum of discussion cutting across issues in electrical, optical, and magnetic ceramics. Driven by the need for miniaturization, cost, and enhanced functionality, the field of electroceramics is growing rapidly in many new directions. The Journal encourages discussions of resultant trends concerning silicon-electroceramic integration, nanotechnology, ceramic-polymer composites, grain boundary and defect engineering, etc.
