为了阐明钯的溶解行为，研究了温度对钯在硼硅酸盐玻璃中溶出量的影响。选择玻璃和氧化钯作为起始材料，混合并在规定的温度下加热。在850℃以上，钯的溶解量随温度的升高而增加，在850℃以上则随温度的升高而降低，在850℃以上，钯的还原速度加快。对于钯在硼硅酸盐玻璃中的溶解，不仅玻璃的粘度和碱度，而且初始钯物种的分解温度似乎也影响着钯在玻璃中的溶出量。
To clarify the dissolving behavior of palladium, the effect of temperature on the amount of palladium dissolved in borosilicate glass was investigated. Glass and palladium oxide, selected as a starter material, were mixed and heated at prescribed temperature. The amount of dissolved palladium became higher with temperature increasing up to 850°C, and lower above 850°C. Above 850°C, the reduction of palladium oxide was accelerated. For palladium dissolution in borosilicate glass, not only the viscosity and basicity of the glass but also the decomposition temperature of the initial palladium species seemed to affect the amount of palladium dissolved in glass.
