Ferrite materials have various applications in both environmental and industrial sectors depending upon different parameters such as the preparation technique, precursors and calcination temperature …..etc. Thus, the ferrite materials have the soft power of sustainable economic development depends on its integration into many applied fields. Our school had a lot of researches in the technology of manufacturing these materials. This report aims to shed light on one of the important ways to prepare ferrites and how to characterize these materials and the most important industrial and environmental applications.
The science and technology of nanomaterials has brought about a great scientific and technological revolution in all areas closely related to economic development. Ferrite materials had the largest share in this scientific development, especially in the field of ferrite manufacturing. The main objective was to obtain ferrite materials in the nano- scale to reach a product with a high specification that gave much higher efficiency than the conventional product. Preparation techniques were the driving force to obtain the ferrite nano particles. Various method had used to preparation of ferrites. Different techniques have been suggested for the preparation of nanophase materials namely vapour deposition, ball milling technique, reversed micelles, Langmuir–Blodgett film, self-assembled monolayers and sol– gel process. In addition, the combustion synthesis (CS) has also been used for the preparation of nano-composite materials [1-7].
Combustion synthesis or self-propagating high-temperature synthesis (SHS) is an effective, low-cost method for production of various industrially and environmentally useful ferrite materials [8-12]. The solution-combustion is a two-step process viz. (i) formation of a precursor and (ii) auto-ignition. The formation of the precursor (viscous liquid or gel), is a primary condition for an intimate blending of the starting constituents and preventing the random redox reaction between a fuel and an oxidizer. The very high exothermic generated during combustion manifests in the form of either a flame or a fire and hence, the process is termed as auto-ignition process [13-15].
Our research group has attended many ferrite materials and has been characterized and studied the surface and catalytic properties of some of them and the magnetic properties of these ferrites have been determined. Glycine and urea were the most important materials as fuels used in the preparation process [8-12].
The different trends on using of ferrites for environmental protection technology were reviewed, 1) treatment of the waste water, 2) formation of carbon as solar hydrogen carrier in presence of excess ferrites via the decomposition of carbon dioxide, 3) solar energy conversion into hydrogen energy and 4) hybridization process for mixing solar and fossil energies . Production of new advanced ferrite composite materials which can use for manufacturing various types of industrial products like: Electric motors, Electric guitar pickups and Sensors….. etc, is one of the important materials in the industrial sector.
