An intergrown perovskite wollastonite phase in some

Abstract. During crystallization of silicate liquids, TiO 2 tends to form its own mineral. Ferrous blast furnace slags generally have perovskite as the titanium rich phase. However, a rounded and fibrous phase, crystallizing instead of perovskite, has been observed in some slag samples it has an apparently late position in the order of crystallization.

High Crystallization of Perovskite Film by a Fast Electric

Herein, we demonstrate a new method to get high crystallization of perovskite film by electric current annealing for just 5 s. In contrast to conventional thermal annealing, a homogeneous perovskite film was formed with larger grains and fewer pinholes, leading to a better performance of the device with higher open circuit voltage and fill factor.

Full CO conversion is reached at temperatures as low as 180 degrees C. The key point seems to be the cooperation of Au and Cu and the optimal metal oxide contact derived from the synthesis method. The high activity of gold for low temperature CO oxidation and the suitability of copper for the WGS results in a perfect synergy.
