We investigated the use of metallic silver as a catalyst for flash sintering on hydroxyapatite/zirconia (HZ) composites. Adding 3 wt% of silver to the ceramic powder reduced the flash onset temperature (from 1084 °C to 925 °C) and also the electric

Reactive flash sintering (RFS) of a chemically prepared multiphase precursor powder was performed to fabricate Li6.25Al0.25La3Zr2O12 (Al-LLZO) ceramics. This approach allowed for obtaining single-phase dense samples in a remarkably short processing t

This work explores a chemical synthesis route and, for the first time, laser processing of ionic conductor Li0.5La0.5TiO3 (LLTO) ceramics. The laser sintering technique has been efficient in producing highly dense single-phase ceramics in just a few

A three-phase system consisting of alumina (Al2O3), magnesia (MgO) and 8 mol% yttria‐stabilized zirconia (8YSZ) was reactive flash sintered to produce MgAl2O4-8YSZ composites. We show that a critical volume fraction of the ionic conductor 8YSZ is r

We show that powders of bismuth titanate, copper oxide, and titanium oxide can be transformed into a single Bi2/3Cu3Ti4O12 phase and subsequently flash sintered at furnace temperatures of 855−910 °C in a single running experiment, with an electric

We investigate the reactive flash sintering of Mg0.2Ni0.2Co0.2Cu0.2Zn0.2O precursor powders prepared by a polymeric synthesis route. The flash experiments were performed at a constant heating rate of 10 °C min−1 with electric fields from 15 to 60

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 powd

Eu-doped (Y2.99-xGdx)Al5O12 phosphors (with x = 0, 0.5, 1, 1.5, 2, 2.5, and 2.99) were prepared by a sol-gel method using polyvinylalcohol (PVA) as gel agent. The crystal structures were characterized through X-ray diffraction and the resulting data
