WebНаучный рецензируемый медицинский журнал "Известия вузов. Порошковая металлургия и функциональные покрытия" WebHexagonal Dy2TiO5 forms Pnma directly, although a small amount of remnants of hexagonal Dy2TiO5 is observed even at the highest pressure (∼55 GPa) reached, indicating kinetic limitations in the hexagonal Dy2TiO5 phase transformations at high pressure. Decompression of these materials leads to different metastable phases. WebDysprosium-titanate (Dy 2 TiO 5 ), being highly refractory in nature, its dissolution using conventional (hot-plate and fusion) methods is very difficult. Hence, for quantitative dissolution, a microwave method has been developed. The instrumental parameters and amount of acids has been optimized.
