The principal advantage of ferrite as compared to conventional sensor based on semiconductor materials of metal oxides is the ability to adjust their band structure , the nature of the active sites on the surface , changing the cation composition . The main conclusion of the published work to date is the discovery of the high sensitivity of the functional properties of iron cation composition and microstructure : crystallite size and pore specific surface area materials.
In our laboratory, conducting research systems mixed ferrites . Samples were synthesized on a specially designed installation spray pyrolysis Pyrola v1.2 based aerosol generator Albedo IN- 7. This provides a one-step method of synthesis of a specific surface area of 150 m2 / g and a high yield of the desired product.
