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掳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聽in-situ聽X-ray measurements. The experiments were conducted at a constant heating rate with fields from 80 to 120鈥疺 cm鈭�1聽and a current limit of 60鈥痬A mm鈥�2. The resulting polycrystal yielded a bulk conductivity of 0.5鈥痬S cm鈥�1.
