| titleOfInvention | The mixture for the manufacture of ceramics based on silicon nitride and the method of making ceramics |
| abstract | The invention relates to the production of instrumental ceramics and makes it possible to increase the strength, hardness and crack resistance of articles thereof. To this end, the charge comprising silicon, dispersion-strengthening additive moiety - titanium nitride of 0.5 - 20.0 wt%, sintering activator -. Yttrium aluminum garnet 1.0 - 7.0 wt% titanium hydride administered TIH N 5. 0 - 30.0 wt.%, Where N≥2. Ceramics are made by mixing the components, shaping the blanks, nitriding and sintering them, and nitriding is carried out by heating at a rate of 15-20 ° C / min to 800- 900 ° C and aging at this temperature for 30 minutes until complete decomposition of TIH N and then heating to 1100 - 1200 ° C and holding until complete nitriding. The resulting material has a flexural strength of 80 - 870 MPa, K 1 @ 8.5 - 9.0 MPa . m 1/2n n n Vickers hardness HV 16.5 - 18 GPa. 2 tab. |
