Isothermal section of the Al2O3–TiO2–La2O3 phase diagram at 1400 °C is constructed for first time. It part systematic investigations Al2O3–TiO2–Ln2O3 (Ln = lanthanides, Y) systems. The was taken as temperature, which no liquid expected in system. Samples were prepared by a chemical method. annealed air 80 hour sand cooled furnace. Phases samples determined XRD analysis. New phases and appreciab...

Aims. To trace the source of the unique 13, 19.5, and 28 μm emission features in the spectra of oxygen-rich circumstellar shells around AGB stars, we have compared dust extinction spectra obtained by aerosol measurements. Methods. We have measured the extinction spectra for 19 oxide powder samples of eight different types, such as Ti-compounds (TiO, TiO2, Ti2O3, Ti3O5, Al2TiO5, CaTiO3), α-, γ-,...

Nucleation is a fundamental part in most syntheses of ceramic materials. Yet, few techniques enable control this step, which would offer possibilities to attain full-scale kinetic selectivity the reach novel compounds with unique properties. Herein, we present nucleation-controlled crystallization pathway synthesize coatings aluminum titanate (Al2TiO5)─renowned for its low-to-negative thermal e...
