Phase transitions in casting process of beryllium oxide slip

Abstract

Beryllium oxide slip casting is used to obtain products of complex shapes of various designs. Ultrasonic activation improves the rheological properties of the beryllium oxide slip. In experiments with ultrasonic activation, physicochemical properties of a beryllium oxide slip were obtained. The calculated beryllium oxide casting data was obtained using the Balkley-Herschel model. The phase transition from liquid to viscousplastic state indicates the presence of a crystallization zone consisting of liquid and solid particles of beryllium oxide. Comparison of calculated data with experiment is presented.
