CHARGE FOR PRODUCTION OF CERAMIC MATERIAL (VARIANTS) Russian patent published in 2024 - IPC C04B35/44 C01F7/168 

FIELD: ceramic materials science.

SUBSTANCE: invention relates namely to the charge compositions for the production of ceramic material for structural purposes. The charge contains a mixture of γ-aluminium oxide, barium carbonate and oxide additive. According to the first option, the charge contains iron (III) oxide as an additive in the following ratio of components, moles: γ-Al₂O₃ 5-5.5; BaСO₃ 1; Fe₂O₃ 0.5-1. According to the second option, the charge contains manganese (III) oxide as an additive in the following ratio of components, moles: -Al₂O₃ 5-5.5; BaСO₃ 1; Mn₂O₃ 0.5-1.

EFFECT: increasing the compressive strength of the claimed ceramic materials to 276.9-562.5 MPa.
