摘要： The present invention is able to provide a method for producing solid electrolyte particles, the method comprising a step (1) in which solid electrolyte particles are precipitated by bringing a good solvent solution and a poor solvent into contact with each other, the good solvent solution containing a good solvent and a solid electrolyte that contains Sn, S and at least one of an alkali metal element and an alkaline earth metal element. The present invention is also able to provide a method for producing an all-solid-state battery, the method comprising a step in which an all-solid-state battery is formed by stacking a solid electrolyte layer, which is formed using solid electrolyte particles produced by the above-described method, a positive electrode layer and a negative electrode layer.

摘要： What is provided is stannous oxide having an α-ray emission amount of 0.002 cph/cm 2 or less after heating in an atmosphere at 100°C for 6 hours. Tin containing lead as an impurity is dissolved in a sulfuric acid aqueous solution to prepare a tin sulfate aqueous solution, and lead sulfate is precipitated in the aqueous solution and removed. While stirring the tin sulfate aqueous solution from which lead sulfate has been removed, a lead nitrate aqueous solution containing lead having an α-ray emission amount of 10 cph/cm 2 or less is added to cause lead sulfate to be precipitated in the tin sulfate aqueous solution, and simultaneously the tin sulfate aqueous solution is circulated while removing the lead sulfate from the aqueous solution. A neutralizing agent is added to the tin sulfate aqueous solution to collect stannous oxide.

摘要： The present disclosure is directed to compositions comprising Ce-containing mixed oxides, especially those having a stoichiometry of Ln y Ce x M w O z ; where
0.15 ≤ x ≤ 0.5, y ≤ 0.25, w = (1-x-y) ≥ 0. 5, and z = (2x + 2w + 1.5y);
M is Zr, Hf, Ti, Sn or Ge or a combination thereof;
Ln is Y and/or one or more rare earth metals, exclusive of Ce,
and the uses of these compositions. These compositions are characterized by the even distribution of the Ce in the lattice of the mixed oxide.
