This article describes the process of obtaining VK94-1 ceramics modified with zirconium dioxide ZrO2, in order to determine and compare such properties of the resulting composite material as: apparent density, mechanical bending strength and Vickers hardness (microhardness) with the properties of ceramics VK94-1, as well as the effect on these properties of changes in the percentage of zirconium dioxide in the samples. The influence of the firing temperature on the sintering of samples has been studied. Samples with different component ratios VK94-1/ZrO2 (90/10, 80/20, 70/30) were pressed on an isostatic press at a pressure of 150 MPa. The firing was carried out at different temperatures: 1500, 1550 and 1600 ?C in different firing mediums.
