The aim of this paper is to study the effect of variation in the component ratio of (1−x)Si3N4 - xAl2O3 ceramics on the phase composition, strength and thermal properties of ceramics. To obtain ceramics and their further study, the solid-phase synthesis method combined with thermal annealing of samples at a temperature of 1500 ◦C typical for the initialization of phase ...

This paper considers the effect of adding niobium oxide (Nb2O5 ) to ferroelectric ceramics based on calcium titanate (CaTiO3 ), and establishes a connection between the observed alterations in strength and dielectric properties and the variation in the Nb2O5 dopant concentration in the ceramics’ composition. The method of mechanochemical solid-phase synthesis was used as the ...

The use of nitride ceramics, in particular AlN, as structural materials for nuclear power is primarily limited by their resistance to swelling and hydrogenation processes due to the accumulation of poorly soluble helium and hydrogen ions in the structure of the surface layer. In this regard, research in this area is of great importance not only from a fundamental point of view, ...

Kozlovskiy, A.; Borgekov, D.B.; Zdorovets, M.V.; Kadyrzhanov, K.K.; Shlimas, D.I. Study of Radiation-Induced Damage Processes in CeZrO4–YZrO3 Ceramics Caused by Helium Irradiation. Materials 2023, 16, 198. https://doi.org/10.3390/ma16010198

The paper is devoted to the study of radiation-induced damage kinetics in beryllium oxide ceramics under irradiation with low-energy helium ions with fluences of 1015–1018 ion/cm2 . It was revealed that at irradiation fluences above 1017 ion/cm2 , a decrease in radiation-induced damage formation and accumulation rate is observed, which indicates the saturation effect. At ...

Ceramics based on zirconium dioxide are very important compounds for dental, implant, and structural material applications. Despite the fact that tetragonally stabilized YSZ has been well studied, the search for new compositions of zirconia-based ceramics is still in progress. The ZrO2 -CeO2 system is one of the alternatives for YSZ materials, but there is conflicting ...
