Abstract

For the application of environment conscious glass-fertilizer, dissolution characteristics of phosphate glass was investigated. In 0.1K₂O-0.1SiO₂-0.6P₂O/sub 5/ glass system, the compositions were designed according to variation of CaO & MgO contents, and glass formation region was confirmed. From the glass composition, the confirmed glasses were investigated to figure out thermal and dissolution properties. It was detected that glass transition & softening temperature of the glasses increased with increasing MgO contents. The dissolution properties of the glasses was affected by CaO and MgO content ratio.

환경친화적인 유리비료로서의 응용을 위해 인산염계 유리의 용출특성에 대한 연구를 진행하였다. 0.1K₂O-0.1SiO₂-0.6P₂O/sub 5/계 유리를 기본조성으로 하고, CaO와 MgO의 함량변화를 준 다양한 유리조성에 대한 유리 형성 조건을 확인하고자 하였다. 또한 CaO 및 MgO의 함량변화에 따른 열적특성 및 용출 특성 변화를 확인하였다. MgO 함량의 증가에 따라 유리 전이온도 및 연화온도는 증가하였으며, CaO 및 MgO의 함량변화에 따라 용출특성에 큰 영향을 미치는 것을 확인하였다.
