초록

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.

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.
