Outline of Final Research Achievements

Physical properties (viscosity, thermal conductivity) of silicate liquids and their glasses are important to control the high temperature processes (e.g., glass making and pyrometallurgy). However, it is still difficult to understand the mechanism of property change with a variation in chemical composition because of their multicomponent system. In the present project, viscosity and thermal conductivity of multicomponent aluminosilicate melts and glasses were evaluated. Also, the local structure in the neighborhood of cations in network region and their breakage region were analyzed spectroscopically. It is found that the physical properties should be influenced by coordination number of silicon and aluminum cations in the network structure.

Academic Significance and Societal Importance of the Research Achievements

放射性廃棄物のガラス固化プロセスなど、トライアル&エラーによる最適化が困難な高温プロセスでは、プラントや溶融炉等の設計時点で詳細なプロセスシミュレーションが不可欠である。酸化物を溶解し、スムーズに流し出すには、融体やガラスの熱伝導率や粘度は特に重要な物性値であると言える。本課題で得られた知見は、工業的に扱われる多成分系酸化物融体の物性発現メカニズムの理解を進展させ、組成設計の指針となると期待できる。
