Beryllium oxide (BeO) ceramics formed with the use of ultrasound exhibit more intense sintering, lower shrinkage, and a reduced sintering temperature compared to ceramics produced without ultrasound. The effectiveness of ultrafast sintering is dependent on the cohesion of ceramic agglomeration and the proper arrangement of particles. Rheological properties thermoplastic slurry changed as a result of ultrasound activation. These changes are related to dispersion phase processes and mass transfer. Ultrasonic activation also slightly enhances the properties of the castings. The increase in the density and strength of castings is explained by the effective reduction of shrinkage under the influence of ultrasound during hardening. That is, compensation for the deposition of the Ingot is determined by filling with a liquid slurry and its compaction under the influence of pressure. For ultrasonic injection of thermoplastic beryllium oxide slurry, formulations with a binder content ranging from 9,5 to 11,7% are recommended. Because these binder compositions are mixed with beryllium powder, turning into a high-strength slurry, forming ceramics that can withstand large temperatures.
