Abstract: PROBLEM TO BE SOLVED: To obtain a spinel strucure having a specified specific surface area and a composition, from which elution of Mn is suppressed by mixing a lithium raw material and a manganese raw material in a specific ratio, then firing the obtained mixture under an oxygen atmosphere, further adding and mixing and additional lithium raw material and firing the obtained mixture under an oxygen atmosphere at a particular temp. SOLUTION: LiOH used as a lithium raw material and MnO2 or the like used as a manganese raw material are mixed in the molar ratio of Li to Mn of 1:2. The obtained mixture is subjected to the first firing under an atmosphere containing gaseous oxygen in an amount of not less than that of gaseous oxygen contained in the atmosphere, thereby a lithium-manganese oxide having stoichiometric composition is synthesized. Thereafter, LiOH being the lithium raw material is added to the oxide to that the molar ratio of Li to Mn becomes higher than 1:2 and lower than 4:5. The obtained mixture is subjected to second firing at a temp. of less than the temp. at which oxygen begins to be released. Thereby, the lithium-manganese oxide with spinel-type crystal structure, having a BET specific surface area of 0.1 to 1 m2/g and being expressed by the formula [Li](8a)[LixMn2-x](16d)O4+y(32e), (0

Abstract: PURPOSE:To provide a method for producing caustic soda without producing chlorine together by using sodium chloride as a raw material. CONSTITUTION:Sodium nitrate and calcium chloride are produced by using sodium chloride and calcium nitrate as the raw materials by electrodialysis. Next, caustic soda and nitric acid are produced by using the formed sodium nitrate as a raw material by electrolysis. Then, calcium nitrate and hydrochloric acid are produced by using the nitric acid and the calcium chloride by electrodialysis. The calcium nitrate is used in circulation while sodium nitrate is allowed to thermochemically react with metal copper at 800-1200 deg.C to form sodium oxide.
