A. Daniel Jones And Hui Li, Ars Technica, 19 Aug. 2022 The TiCl4 then must be vacuum distilled to purify it, and the vapor is fed into a reaction vessel containing molten magnesium blanketed in inert argon gas and heated to 800 - 1000ºC for about two days. Willy Shih, Forbes, 10 July 2022 Inside, the atmosphere is mainly argon, the least reactive of gases, reducing the chance of impurities that cause defects in a part.
