1. Absorbing materials
Nanometer ZnFe2O4 material, as a kind of absorbing material, can effectively absorb, reflect and scatter the electromagnetic wave of radar projected to its surface in radar application band, and convert the electromagnetic wave energy into heat energy or other forms of energy, thus greatly reducing the electromagnetic wave reverse on the material surface. Under static conditions, nano-zinc ferrite materials exhibit ferromagnetism. When the external magnetic sound ACTS, nano-zinc ferrite will magnetize. Nanometer zinc ferrite materials have certain dielectric properties. When in an alternating magnetic field, the magnetization of nanometer zinc ferrite materials will lag behind the change of external field with the change of frequency, so that magnetic energy and electrical energy can be stored to generate electromagnetic energy loss. There have been reports that some of the us b-2 bombers used ferrite as a wave absorbing coating. As nanometer zinc ferrite material applied in absorbing wave, it is the most widely used absorbing material in both modern military equipment and civil applications.
2. Photocatalytic degradation
Nano zinc ferrite is a narrow band gap semiconductor material, and the introduction of TiO2 can redshift the light absorption edge, thus extending the spectral response range of TiO2. At the same time, the addition of zinc ferrite also promotes the crystal transformation of TiO2, enabling it to obtain a better proportion of mixed crystals at a lower calcination temperature. Experiments have proved that TiO2 doped with 2% ZnFe2O4 has the best photocatalytic effect when calcined at 500鈩.
