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.
