説明

<p>Ashes and harmful gasses from volcanoes lead to the air pollution and severe problems for health damage and agriculture. In special, volcanoes more than 50 in Japan are volcanically active and often product a large amount of volcanic ashes. The recycle for waste of volcanic ashes pose a severe problem to the lives of residents near the volcano. The volcanic ashes are composed mostly of SiO2. In this study the syntheses of zeolite from the waste of volcanic ash including SiO2 were attempted through the hydrothermal solution process. The relation between the process of hydrothermal solution process and microstructure of obtained zeolites was investigated and also ion exchange ability against Sr ion was evaluated.</p>
