“…For example, incorporating a metal chloride into the GeS 2 –Ga 2 S 3 system produces mobile complex anions of MGaS 3/2 Cl, resulting in glass formation . Further, increasing the CsI contents in GeS 2 –In 2 S 3 tends to decrease the glass transition temperature and even the formability of glasses with a softening point below room temperature has been demonstrated in the GaI–NaCl system . Various metal halides have also been introduced in chalcohalide or fluoride glasses to improve glass-forming ability and lower the glass transition temperature by forming complex anions. , …”

The key challenges in all-solid-state batteries (ASSBs) are establishing and maintaining perfect physical contact between rigid components for facile interfacial charge transfer, particularly between the solid electrolyte and cathode, during repeated electrochemical cycling. Here, we introduce inorganic-based pliable solid electrolytes that exhibit extraordinary clay-like mechanical properties (storage and loss moduli <1 MPa) at room temperature, high lithium-ion conductivity (3.6 mS cm −1 ), and a glass transition below −50°C. The unique mechanical features enabled the solid electrolyte to penetrate into the high-loading cathode like liquid, thereby providing complete ionic conduction paths for all cathode particles as well as maintaining the pathway even during cell operation. We propose a design principle in which the complex anion formation including Ga, F, and a different halogen can induce the claylike features. Our findings provide new opportunities in the search for solid electrolytes and suggest a new approach for resolving the issues caused by the solid electrolyte−cathode interface in ASSBs.

“…This glass material is widely used in infrared imaging applications due to its transmission in mid-wavelength infrared (3–8 µm) and part of the long-wavelength infrared (8–15 µm). The physical properties of this glass are published in the glass datasheet, as well as its Abbé number in the literature [ 13 ], as summarized in Table 1 . Its Young’s modulus, listed in Table 1 , exhibits low rigidity, even if compared with other ChG glasses [ 13 ].…”

Simulation of the Refractive Index Variation and Validation of the Form Deviation in Precisely Molded Chalcogenide Glass Lenses (IRG 26) Considering the Stress and Structure Relaxation

et al. 2022

Precise infrared (IR) optics are core elements of infrared cameras for thermal imaging and night vision applications and can be manufactured directly or using a replicative process. For instance, precision glass molding (PGM) is a replicative manufacturing method that meets the demand of producing precise and accurate glass optics in a cost-efficient manner. However, several iterations in the PGM process are applied to compensate the induced form deviation and the index drop after molding. The finite element method (FEM) is utilized to simulate the thermomechanical process, predicting the optical properties of molded chalcogenide lenses and thus preventing costly iterations. Prior to FEM modelling, self-developed glass characterization methods for the stress and structure relaxation of chalcogenide glass IRG 26 are implemented. Additionally, a ray-tracing method is developed in this work to calculate the optical path difference (OPD) based on the mesh structure results from the FEM simulation. The developed method is validated and conducted during the production of molded lenses.

“…Ternary glass alloys could be formulated by inserting an appropriate additive element into the binary matrix. A ternary (As-S-Se) system has a very broad glass-forming region [2,[5][6][7][8][9]. Solid solutions could be developed across the line As2S3-As2Se3, which has been proven by Velinov and his coworkers through IR spectra and x-ray evaluation [10].…”

“…The structure of chalcogenide components has been extensively studied in binary compositions, whether bulk or thin-film. Several binary substances can be formulated by attaching one of the chalcogens with another element like As, Sn, Ag, In, Pb, Al…etc [2].…”

This framework focuses mainly on a detailed study of the pre-crystallization criteria that characterize the As40S45Se15 glassy alloy in various heating rates ranging from 5 to 40 (K/min.) by DSC thermo-grams in the range of (300-575 K). These criteria aim to clarify the relationship of the tendency of glass-forming by the heating rate for the investigated glassy alloy. As well, the present framework demonstrates the criteria of thermal stability.Continuously, the various nucleation and growth pathways. The transformation in activation energy with the volume of the crystalline portion was deduced and, through this, we were able to determine the surface resistance of the analyzed bulk alloy in the crystallization region. The crystalline structure of the study sample was recognized by X-ray diffraction (XRD) and electron scanning microscope (SEM).
