[0026] A preparation method of zinc ferrite material, comprising the steps of:
[0027] Ingredients: raw materials include iron acetylacetonate, zinc acetylacetonate, surfactant and solvent; the solvent is dibenzyl ether or 1-octadecene or oleylamine;
[0028] Wherein, the molar ratio of zinc acetylacetonate and iron acetylacetonate is 0.1~0.8, the molar ratio of the total amount of iron acetylacetonate and zinc acetylacetonate to surfactant is 0.01~0.85, and the amount of solvent can fully dissolve iron acetylacetonate and acetylacetonate Zinc;
[0029] The raw materials are placed in a protective gas environment, mixed at room temperature; and then the product particles obtained after slow heating, rapid heating and cooling are the zinc ferrite materials.
[0030] The chemical formula of the zinc ferrite material prepared by the above method is: Zn X Fe 3-X o 4 ; where: 0<X<0.53.
[0031] What is to be explained here is: through the reasonable ratio of iron acetylaceton...
