| titleOfInvention | A kind of method of coated with silica magnetic ferric oxide nano particles |
| abstract | The present invention relates to a kind of method of coated with silica magnetic ferric oxide nano particles, belong to nano material preparing technical field, mainly comprise: utilize known method to prepare water-soluble magnetic ferric oxide nano particles; Add appropriate surface modifier to make stable aqueous-based dispersions; In aqueous-based dispersions, add elemental metals silica flour, add thermal agitation, under the catalysis of alkaline matter, make silica flour hydrolysis, generate silica deposit on magnetic ferric oxide nano particles surface, obtain coated with silica magnetic ferric oxide nano particles. The method does not need with an organic solvent and surfactant in preparation process, and coating reaction is carried out in the aqueous solution, and preparation technology is simple, environmental protection, and raw material is easy to get, with low cost, can realize large-scale industrial production. Products therefrom pattern controllability is strong, and high purity is particularly suitable for biomedical applications. In addition, it is coated that the method can also be widely used in other nanocrystalline SiO2, as quantum dot, noble metal nano particles etc. |
