Abstract
Oxide Y2.5Nd0.5Al5O12 with the structure of the garnet mineral has been obtained by coprecipitation after annealing at 1000°C. Fine-grained ceramics has been produced by spark plasma sintering based on synthesized powder. The relative density of the ceramics was 99.1%. The chemical stability of the ceramics has been studied in static mode at 90°C in distilled and mineral water, acidic solution, and alkaline solution. The minimum rates of Y and Nd leaching were 10–10 to ~10–6 g/(m2 day). The effect of the contact environment on the rate and mechanism of Y and Nd leaching from the Y2.5Nd0.5Al5O12 ceramics was studied during 42 days.
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
