Calculation and Application of Glass Lubricant Viscosity–Composition LIN Ben, WANG Baoshun, ZHANG Maicang, DONG Jianxin School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing, 100083 Correspondent: DONG Jianxin, professor, Tel: (010 E-mail: jxdong@mater.ustb.edu.cn Supported by National Natural Science Foundation of China (No Manuscript received 2010–09–28, in revised form 2010–11–21 ABSTRACT Based on the classical first–order mixture method which describes the relationship between the property value and component, a modified mixture method for predicting the viscosity property of borosilicate glass lubricant used in the hot extrusion of G3 alloy was established. Then, the viscosity properties of 10 different borosilicate glasses were predicted using this method. The viscosity data predicted by this calculation method coincided well with the experimental data, which showed that the calculation model was of strong reliability. Therefore, according to this model, the glass composition could be reversely designed, which will assure the viscosity of glass to meet the requirements of glass lubricated hot extrusion of G3 alloy which has been raised in the first article. It provides theoretical guidance for the design an
