TL;DR: In this paper, a new cell concept for the calciothermic reduction of titanium dioxide and an ongoing test program for its experimental verification is presented, where both the reduction reaction and the electrolytic reaction for recovery of reducing agent coexist in the same molten calcium-chloride bath.

TL;DR: In this paper, a concept for direct reduction of titanium dioxide in molten CaCl2 is proposed and experimentally tested, where both the thermochemical reaction of the calciothermic reduction and the electrochemical reaction for recovery of the reducing agent, Ca, coexist in the same molten caCl2 bath.

TL;DR: In this article, a new cell concept for calciothermic reduction is presented where TiO 2 is used as the raw material for reduction and the reduction system consists of a single cell, where both the reduction reaction and the electrolytic reaction for recovery of reducing agent coexist in the same molten CaCl 2 bath.

TL;DR: The compositional region in the Ca-CaCl2-CaO system was examined for the less oxygen contamination in Ti and the better handling in leaching as mentioned in this paper, and the metallic Ti powder less than 1000 mass ppm oxygen could be obtained only for 3.6 ks using 5 to 7 mol pct Ca-CACl2 at 1173 K.

TL;DR: This study reports a new self-ordered nanoporous alumina formed by selenic acid (H2SeO4) anodizing without any special electrochemical equipment that can be used as a nanotemplate for various nanostructures in 10-/sub-10-nm-scale manufacturing.
