The paper presents comparative studies of physical-mechanical properties of long-measured/elongated corundum-zirconium ceramic with different phase ration, manufactured with the use of the radial magnetoimpulse press. The optimal mode of pressing of ultra-dispersed powders was developed, where the amplitude of magnetoimpulse pressure is 1.14 GPа at acceleration time-120 mcs. We obtained the corundum-zirconium ceramic with the grain size 0.35-0.5 μm and the coherent-scattering regions of 0.050-0.120 μm, possessing microhardness 10.6-12.9 GPа and crack-resistance 5.5-7.8 MPа·m1/2.
