FIELD: chemistry. ^ SUBSTANCE: invention relates to methods of producing alumina ceramic material meant for making articles from structural ceramic with high static loads. According to the invention, alumina is mixed with a mineralising agent characterised by viscosity of 1-5 Pas and surface tension (50-250)10-3 N/m a temperature interval for burning ceramic in amount of 1-2 wt % on the cation-oxygen component. Sinter is obtained at 1300C. The sinter is ground, pressed and burnt at 1350-1400C. The mineralising agent used is in form of chlorides of alkali and alkali-earth metals KCl, MgCl2, LiCl, CaCl2, NaCl, BaCl2. ^ EFFECT: high ceramic sintering temperature with increase in ultimate bending strength. ^ 2 tbl |
