  • Method of toughening alumina
    Patent number: 9040440
    Abstract: The present application is directed to a zirconia toughened alumina body and process for making the body. The process involves combining tetragonally stabilized ZrO2 nanoparticles, Mg(OH)2 particles and alumina powder into a mixture. All particles of the mixture are milled, formed into a green compact and then sintered. The final composition of the body includes ?-Al2O3 toughened with 0.5 to 2.5 weight percent ZrO2 in a stabilized tetragonal form and 0.03 to 0.10 weight percent MgO. The composition results in an Al2O3 body with a density less than 4.0 g/cc and strength greater than 50 kpsi.
    Type: Grant
