Abstract

The paper discusses a method for obtaining a ceramic material composition for further use in investment casting. Based on electrocorundum and silica-free binders, prototypes of Al₂O₃ ceramics were produced. The quality of the front layer was assessed and the manufactured samples were tested. It was revealed that the mechanical properties of the obtained ceramic materials do not meet the required ones, which led to measures aimed at improving the mechanical characteristics of ceramics, in particular the use of sintering additives.

Keywords

investment casting, water-based binder, alumosol, electrocorundum, ceramic shell mold,
