内容記述タイプ | Other | |||||
内容記述 | In order to characterize the potassium-chabazite (K-CHA) obtained by hydrothermal synthesis with KOH from coal fly ash, various physical properties such as crystal structure, textures of surface and cross section of particles, cation exchange property, acid-resistance and heat-resistance were investigated for the synthesized K-CHA product. The particle size of the K-CHA product has a maximum point at 20μ and a shape distribution. The particles of K-CHA consist of unreacted coal fly ash or coagulated fine particles of K-CHA as a nuclear. In case of pH over 4, the X-ray diffraction intensity of K-CHA decreases with a decrease in pH, but K-CHA crystals are not dissolved. On the other hand, K-CHA crystals are dissolved in the aqueous solution of pH below 4. In case of heat treatment below 873K, the X-ray diffraction intensity of K-CHA decreases with an increase in temperature, while the thermal decomposition of K-CHA and production of new crystalline materials do not take place. In the heat treatment of 1,273K, the peaks of K-CHA disappear in the XRD pattern and those of leucite newly generate. The K-CHA product contains about 10% of water and about 3% of unburned carbon. |
