摘要
On the basis of Wang's work[4] and optimization principle, the constant C6 in the equation for calculating the reference melting temperature of silicate glasses has been re-evaluated by coordinate rotation method, by which the multi-dimensional optimized calculation has been transferred into some one-dimensional optimized calculations. This method is simple in calculation and less in deviation, so it is suitable for the glasses with wide range of lime content (wt %)in composition. By comparing the calculations with the experimental data of 60 different glasses, it has shown that the deviations and differences within the range of ±28℃ and ±52℃ between the calculated values and experimental data of melting temperature are 75% and 95%, respectively. The deviation of the calculation of this method is less than that of Wang's result, the method is, therefore, useful in practice.
