The state of ZnO/γ-Al_2O_3 samples was observed by transmission electron microscopy. The crystalline substances in the samples were identified by electron diffraction experiment. The main view points mentioned in the previous paper[1] were demonstrated intuitively.
The reaction between ZnO and γ-Al_2O_3 can occur easily.The lattice constant of the formed Zn_xA1_2O_(3+x) is slightly larger than that of γ-Al_2O_3. It can be observed by THM that when ZnO content is higher than a certain value, crystalline ZnO begins to appear. The higher the temperature of calcination, the larger the value.
