Improvement of the Technology of Corundum Armor Materials Modified with Eutectic Additives

This study presents research data on three powder compositions obtained via laser ablation. The mixtures consist of aluminum oxide (Al2O3) and zirconium oxide (ZrO2) in varying proportions — 10, 20, and 30 wt.%, respectively. We have analyzed the precursors using scanning electron microscopy (SEM), X-ray diffraction (XRD), and beta-electron fluorescence (BET). The molded specimens were sintered at temperatures ranging from 1500 °C to 1600 °C. We determined key characteristics of final ceramic products: density, porosity, and flexural strength. From each composition, the sample with the highest flexural strength was selected for microstructural analysis of the cross-section using SEM. The study investigated the influence of zirconium dioxide additives on the phase composition and mechanical properties of corundum-based armor ceramics, as well as the optimal synthesis parameters.
