  • Preparation and application of cube-like ZnSnOcomposite coated with highly graphitized fine ash
    Patent number: 11760883
    Abstract: A preparation method of a cube-like ZnSnO3 composite coated with highly graphitized fine ash comprises steps: S1: with the gasified fine slag of pulverized coal as a raw material, preparing the fine ash by adopting a three-step acidification method; and S2: adding the fine ash prepared in the S1 into a container filled with distilled water, ultrasonically dispersing for 20-40 min, adding equal molar masses of SnCl4·5H2O and (Zn(NO3)·6H2O respectively, uniformly stirring, dropwise adding ammonia into the mixed solution and magnetically stirring until the pH value of the mixed solution is 12, heating the mixed solution, washing the product obtained with deionized water and ethanol for 2-4 times, and finally drying to obtain a ZnSnO3@fine composite. With the dielectric property and conductivity adjusted, the composite prepared reveals a good impedance matching performance and an improved MA performance.
