Abstract

The possibility of application of electroconsolidation for production of ultradenced ceramics based on Al2O3 and ZrO2 (3% Y2O3) compounds is studied. As a result of the conducted researches optimum values of process temperature at which the best parameters of Al2O3 and ZrO2 (3% Y2O3) ceramic properties are reached: the apparent density – 3.98 and 6.08 g/cm3, bending strength – 350 and 800 MPa, fracture toughness – 4.0 and 8.0 МPa⋅m0.5 respectively are established. The researches of a ceramics microstructure are found that high parameters of Al2O3 and ZrO2 (3% Y2O3) properties are defined by dense and fine-crystalline structure.
