采用降温式量热计对六个MOSiO_2(M=Li_2,K_2 Sr和Ba)熔体,二个钛的碱性硅酸盐熔体在900—1800k温度下进行了量热测定.根据测定结果并参照各类文献中已发表的数据,推导出作为温度和化学成分的函数来计算无铝硅盐熔体热容的模型.分析了21个主要元素氧化物和微量元素氧化物,除含K_2O的熔体外,其结果均表明热容的变化并不是成分的加和函数.简便的能量计算说明,液体温度的
The calomel results of six MOSiO_2 (M = Li_2, K_2Sr and Ba) melts and two titanate silicate melts were carried out at 900-1800k by calorimetry.According to the results With reference to the published data in various literatures, a model for calculating the heat capacity of aluminum-free aluminum silicate melt as a function of temperature and chemical composition was deduced.The 21 major oxides and trace oxides were analyzed, except K 2 O Melt, the results show that the change of heat capacity is not an additive function of composition. Simple energy calculation shows that the liquid temperature
