Technological peculiarities of obtaining of powders BeO and beryllium ceramics by method of casting slurry

Abstract

The technology of obtaining a powder of beryllium oxide and ceramic products is presented in the article. To
obtain and improve of the quality of ceramic products and increase of casting efficiency was used in practice, an effective high-performance technology - processing of thermoplastic slurry by ultrasonic action. At the molding stage the cast ability of thermoplastic slurry depends on the viscosity and yield strength. Dependences of the consistency of slurries on the volume content of the solid phase at different temperatures were determined. The analysis of experimental initial data for the construction of a correct model of casting processes is carried out. During the analysis, the viscosity, yield strength and density of thermoplastic slurry ont the temperature were determined for various compositions.
