Viviana and LÃlian publish paper on Reactive flash sintering of the complex oxide Li0.5La0.5TiO3 starting from an amorphous precursor powder
Abstract
We report the transformation of an amorphous mixture of Li0.5La0.5TiO3(LLTO) directly into a single phase dense polycrystal, all within a few seconds at about 800°C by the flash method. The starting material is a chemically-prepared precursor powder that experiences concurrent crystallization and densification to cubic LLTO during the flash event, as shown by in-situ X-ray measurements. The experiments were conducted at a constant heating rate with fields from 80 to 120 V cm−1 and a current limit of 60 mA mm–2. The resulting polycrystal yielded a bulk conductivity of 0.5 mS cm–1.
