“…For example, Tatsumisago successfully stabilized α‐AgI in AgI–Ag 2 O–B 2 O 3 glass‐ceramic at room temperature through a twin‐roller rapid quenching technique . Meanwhile, conductivity of AgI‐based phosphate glasses can be enhanced after appropriate crystallization process . Compared with glassy oxides, chalcogenide glassy electrolytes are particularly promising for the high ionic conductivity and superior ductility allowing for room‐temperature processing, which makes them more suitable for use in all‐solid‐state batteries .…”

The glass‐ceramics of AgI‐based electroconductive chalcogenide system was realized using an appropriate heat treatment at a fairly high temperature (Tg + 40°C) and different times ranging from 4 to 20 hours. The crystallization behavior and electroconductive properties of the heat‐treated samples were studied in detail. Transmission study was performed, and the results show that the cut‐off edge of the short wavelength is red‐shifted at prolonged annealing time but remains an excellent transmittance in the mid‐infrared (IR) region. XRD and scanning electron microscopy results indicated that the precipitated crystalline phases are mainly β‐/γ‐AgI. Moreover, a small amount of α‐AgI, which rarely existed at room temperature, is precipitated in the AgI‐rich chalcogenide glass‐ceramics. The ionic conductivity of all glass‐ceramics was enhanced by heat treatment in contrast to that of base glass. Raman analysis exhibited the structure variation in the glass sample after heat treatments. This study provided an observation of crystallization in chalcogenide glass containing large amounts of AgI and be of good guidance to fabricate novel AgI‐based chalcogenide glass‐ceramics that can be candidates in infrared optics and solid electrolyte applications.

“…Silver ion conductive glasses of the systems AgI-Ag 2 O-M x O y (M x O y =B 2 O 3 , P 2 O 5 , MoO 3 , etc.) exhibit high electrical conductivity (up to 5·10 −3 S·cm −1 at room temperature) [10][11][12][13][14][15][16][17][18][19][20][21][22][23] of purely ionic character. Glasses with Bi 2 O 3 were found to participate in forming stable glasses with high Bi 2 O 3 content [24][25][26][27][28] .…”
