Abstract
A molybdenum oxychloride or a tungsten oxychloride, wherein the molybdenum oxychloride or the tungsten oxychloride has a moisture content of less than 1 wt %. A method of producing a molybdenum oxychloride or a tungsten oxychloride, wherein a molybdenum oxide or a tungsten oxide as a raw material is subject to dehydration treatment at 400° C. or higher and 800° C. or less, and the raw material that underwent dehydration treatment is thereafter reacted with a chlorine gas to synthesize a molybdenum oxychloride or a tungsten oxychloride. An object of the present invention is to provide a molybdenum oxychloride or a tungsten oxychloride having a low moisture content, as well as a production method thereof.
Claims2
A method of producing a molybdenum oxychloride or a tungsten oxychloride, wherein a molybdenum oxide or a tungsten oxide as a raw material is subject to dehydration treatment at 400° C. or higher and 800° C. or less while flowing inert gas, or inert gas mixed with oxygen, or air (O2+N2), wherein the dehydration treatment time is set to be 3 hours or longer, and the raw material that underwent dehydration treatment is thereafter reacted with a chlorine gas to synthesize a molybdenum oxychloride or a tungsten oxychloride.
