Problems solved by technology

Glass materials that can be used in the mid-infrared band, fluoride glass is a typical representative, which is mainly due to its low phonon energy (450cm -1 ), but at the same time, fluoride glass also has inherent defects, such as brittleness and fragility, low tensile strength, easy to be eroded by moisture, poor chemical stability, low thermal damage threshold, difficult to fiberize, and low operating temperature of the fiber body (≤150℃) etc.

Abstract

The invention relates to mid-infrared anhydrous tellurate glass and a preparation method of the tellurate glass. The mid-infrared anhydrous tellurate glass is prepared by the components of: 55-80mol% of TeO2 and 20-45mol% of ZnF2. The mid-infrared anhydrous tellurate glass provided by the invention is anhydrous, capable of satisfying requirements of mid-infrared window glass and signal transmission in an atmospheric window range of 0.3-5 micrometers and expected to be widely applied to national defense industry and economic construction.

Description

technical field [0001] The invention relates to a glass and a preparation method thereof, in particular to a mid-infrared anhydrous tellurate glass and a preparation method thereof. Background technique [0002] Infrared window glass and infrared signal transmission fiber have broad application prospects in the fields of national security and national defense construction, astrophysical detection, and spectroscopy research. Glass materials that can be used in the mid-infrared band, fluoride glass is a typical representative, mainly due to its low phonon energy (450cm -1 ), but at the same time fluoride glass also has inherent defects, such as brittleness and brittleness, low tensile strength, easy to be corroded by moisture, poor chemical stability, low thermal damage threshold, difficult to fiberize, and low working temperature of fiber body (≤150℃) and so on. In comparison, no (less) water tellurite glass has low phonon energy (600-800 cm -1 ) and oxide glass, and at th...
