AB  - In this work, Ge<sub>45</sub>As<sub>40</sub>Se<sub>15</sub> chalcogenide glass was prepared using spark plasma sintering. This method synthesizes glass powder into blocks through a certain temperature and pressure, which is an effective densification and high-precision molding of infrared transparent blocks and lenses. Through X-ray diffraction (XRD) and differential scanning calorimetry analysis, we tracked the gradual evolution of the powder during ball milling and observed the existence of a glass transition temperature in the glass after powder hot pressing. This method can prepare components outside the conventional glass forming region with high hardness and infrared transmittance, providing a simple and economical synthetic approach for preparing chalcogenide glass materials with optical application potential.
