dcterms:description
The subject of this work is the comparison of numerically obtained values of surface tension using different types of models and experimentally measured data of surface tension of oxide systems. The ternary system of CaO-Al2O3-SiO2, which presents simplified base of the casting powders used in technological process, was submitted to the experiment. For mathematic calculation of surface tension the semi empirical models resulting from Butler’s equation and Chou model were evaluated as suitable. Further the functionality of empiric model based on theory of regular ionic solution was tested. The results of simulation were compared with experimentally obtained values of surface tension. With regard to relatively higher temperatures of measurement and character of ternary system a sessile drop method was chosen as optimal method for obtaining experimental data.
