Hexagonal system was prepared using carbon reductant control laws wurtzite structure four feet zinc oxide whisker, using stearic acid sol gel (sol gel) combustion of the spherical zno nanocrystals prepared. The use of waveguide method for the resulting product and phase zinc oxide material, magnetic conductivity and dielectric constant measurements. The results show that within 8 ~ 1 2 GHZ test, four feet of zinc oxide whisker in zinc oxide, zinc oxide nanocrystals and body of the dielectric loss does not change significantly with the increase of the frequency. The microwave electromagnetic performance test showed that four feet of zinc oxide whisker and zinc oxide nanocrystals is a kind of dielectric loss material, has a certain microwave absorption performance, and four feet of zinc oxide whisker dielectric loss is greater than the zinc oxide nanocrystals. The body zinc oxide material basic electromagnetic no loss in this frequency range.
