A new Ti smelting process via. Bi–Ti alloy is proposed. This process comprises reduction of TiCl4 to Bi–10 mol%Ti alloy by Bi–Mg alloy, precipitation of Ti-rich compound from the alloy, and vacuum distillation. In this study, we investigated th

A new smelting process of Ti via Bi–Ti liquid alloy is proposed, which comprises reduction of TiCl4 by Bi–Mg alloy, enrichment of Ti in Bi–Ti alloys, and vacuum distillation of the alloys. In this study, the continuous reduction of TiCl4 by Bi

Presently, most of the cells using BaZr0.8Y0.2O3-δ (BZY20) electrolyte were prepared by a co-sintering process performed between 1400 and 1600 °C. However, during the co-sintering process, Ni diffuses from the anode substrate into the BZY20 electro

Doped lanthanum polyphosphate (LaP3O9) exhibits relatively high proton conductivity. For the practical applications such as the electrolyte of fuel cells, however, its conductivity must be improved by 2 orders of magnitude. Protons are introduced int

The precipitation behavior of Sr-doped LaP 3 O 9 from phosphoric acid solutions was investigated at 190–270 °C in the ambient atmosphere or at 300–360 °C in water vapor (1 atm) for the purpose of obtaining large single crystals and dense plate-
