Abstract: A method for producing a high silicate glass substrate, includes: (1) obtaining a glass precursor containing, as represented by mol % based on oxides, 60% to 75% of SiO2, 0% to 15% of Al2O3, 15% to 30% of B2O3, 0% to 3% of P2O5, and 1% to 10% in total of at least one selected from R2O and R′O; (2) applying first heat treatment to the glass precursor to cause phase separation so as to obtain a phase-separated glass; (3) applying acid treatment to the phase-separated glass to make the phase-separated glass porous so as to obtain a porous glass; (4) drying the porous glass so that a rate of change in mass reaches 10% to 50%; and (5) applying second heat treatment to the porous glass to sinter the porous glass so as to obtain a high silicate glass substrate.

Abstract: A sulfide-based solid electrolyte powder emits photo-luminescence light between a wavelength of 660 nm to 750 nm. A photo-luminescence peak ratio may be 0.2 or more in a Raman spectrum obtained by excitation with light having a wavelength of 532 nm as represented by the following formula: Photo-luminescence peak ratio=integrated intensity of peak in Raman shift region of 4300 cm−1 to 4500 cm−1/integrated intensity of peak in Raman shift region of 400 cm−1 to 450 cm−1.
