摘要：

The novel multi-stage method for preparation of especially pure GexAsySbzS100-x-y-z (x = 10-13; y = 20-23; z = 4-6) glasses is presented. The method includes the stages of deep purification of initial elements using different chemical getters, transport reactions and vacuum distillation. The glass samples with compositions close to stoichiometric ones and a low content of gas-forming impurities are synthesized; their structure, optical, thermal and magneto-optical properties are investigated. The studied characteristics of the samples meet the requirements for their use in the IR optics and are relevant for multifunctional applications.
