PURPOSE:To make it possible to utilize the titled electrolyte in many metal materials, by constituting an electrolyte from 0.5-50wt% of maleic anhydride, 0.1- 10wt% of an electrolyte dissolved in a non-aqueous solvent and the remainder of the non-aqueous solvent and adjusting total water content to 1wt%. CONSTITUTION:A non-aqueous solvent type electrolyte is prepared by constituting the same from 0.5-50wt% of maleic anhydride as a first component, 0.1- 10wt% of an electrolyte as a second component, which is dissolved in a non- aqueous solvent, comprising lithium chloride, quaternary alkylammonium halide or the like alone or a mixture of two or more of said compounds and the remainder of the non-aqueous solvent as a third component and adjusting the total water content to 1wt% or less. This electrolyte can dissolve many metal materials and can be used in the observation of the metal structure of each metal material and the observation of extractive separation of a precipitated phase. |
