Chalcogenide glass has the advantages of low refractive index temperature coefficient, wide spectral transmission range, good optical uniformity, adjustable performance and easy processing, etc. Chalcogenide glass is regarded as the core component material of new generation temperature adaptive infrared thermal imaging system, and has a broad application prospect in many fields such as infrared tracking, infrared guidance, security monitoring, driving assistance and so on. However, Chalcogenide glass itself is a brittle material, and has some performance shortcomings such as low softening temperature, poor temperature resistance, lack of plastic deformation and sensitivity of strength to microdefects, etc. In order to solve the demand for infrared materials in extreme service environment or special application, the research on preparation technology of chalcogenide glass mainly involves three aspects: (1) Design and develop the preparation method of large size and high purity chalcogenide glass. (2) Research on atmosphere melting technology to meet the engineering application requirements of large size chalcogenide glass, and then improve the environmental adaptability of window materials. (3) High energy ball milling, hotpressing and other methods are introduced into the preparation of chalcogenide glassceramics to expand the optional range of infrared optical materials and improve the extreme environmental adaptability of chalcogenide glass materials. Based on the above three aspects, the research progress on the preparation technology of chalcogenide glass was reviewed.
