提出了估算二元复合氧化物比热容的双参数模型。用此模型可估算由CaO、SiO2、TiO2等44个简单氧化物之间形成的二元复合氧化物的比热容,涉及硅酸盐、铝酸盐、钛酸盐、硼酸盐、磷酸盐、碳酸盐、硝酸盐等多个复杂体系。在估算已知的300个二元复合氧化物比热容时,平均误差为3.79 J/(mol.K),标准差为4.97 J/(mol.K)。用此双参数模型还可估算三元复合氧化物的比热容,在估算已知的28个三元复合氧化物比热容时,相对误差的平均值为3.9%,相对误差的标准差为4.3%。
A two-parameter model for estimating the specific heat capacity of binary composite oxides is proposed. This model can be used to estimate the specific heat capacity of binary composite oxides formed by 44 simple oxides such as CaO, SiO2 and TiO2, involving silicates, aluminates, titanates, borates, phosphates, carbon Acid salt, nitrate and other complex system. The average error of 3.79 J / (mol.K) and the standard deviation of 4.97 J / (mol.K) were obtained when the specific heat capacity of 300 binary composite oxides was estimated. Using this two-parameter model, the specific heat capacity of the ternary composite oxide can be estimated. When the specific heat capacities of 28 known ternary composite oxides are estimated, the average relative error is 3.9% and the standard deviation of the relative error is 4.3%.
