Abstract

The influence of the conditions of solid-phase synthesis, the composition of the powder composition, the time of its mechanical treatment and the molding method on the properties of ceramics based on manganese-substituted barium aluminate has been studied. It is shown that it is effective to synthesize a material of stoichiometric composition BaO·Mn₂O₃·5Al₂O₃ with subsequent mechanical treatment of the relevant components for 1 min in the AGO-3 activator, forming by semi-dry static pressing at a pressing pressure of 200 MPa, sintering temperature of 1600°C. In this mode, ceramics with a density of 3.73 g/cm³ and a compressive strength of 680.7 MPa were obtained.
