PROCESS FOR PREPARING THE FERRITE FILM FROM THE ANION LAMINATED COMPOUNDS

摘要

A process for making ferrite film from the anion laminated compounds is presented, which belongs to the art of the preparation of ferrite film. The process includes forming the slurry of M<SUP>II</SUP>Fe<SUP>III</SUP>LDHs as a precursor for coating a substrate to obtain the composite film of M<SUP>II</SUP>Fe<SUP>III</SUP>LDHs, drying and curing the film, and finally calcining at elevated temperature to obtain the ferrite film. It is advantageous in that the micro-meter thick ferrite film which consisted of uniformly dispersed and dense particles, has excellent adhesion, and the LDHs initial materials are low cost, and has a simple synthesis method.
