Sintering of alumina ceramic with 95% Al2O3 [VK 95-1] content with additives of aluminum oxide nanopowder and without it is studied. The increase in strength by 32 ± 3% is ensured by additives of 1.5 ± 0.5 wt %. The strength reaches 170 ± 5 MPa, which allows it to be used as dental prosthesis forms in stomatology.
