The results of tests on the strength, hardness, and fracture toughness (crack resistance) of the studied ceramics are presented, and the influence of sintering modes on these mechanical properties is analyzed. Three sets of experimentally determined data were collected to predict zirconia ceramics' hardness, strength, and fracture toughness based on the given chemical composition, phase composition, microstructure features, and sintering temperature. The hardness, strength, and fracture toughness of zirconia ceramics were simulated using 5 ensemble machine learning methods. The highest prediction accuracy of each of the three mechanical properties was established using ensemble methods of the boosting class (CatBoost, AdaBoost, and XGBoost).  Product Description popup.authors Bohun Lidiia I.
