Problems solved by technology

The preparation method is complicated to operate and has high requirements for safety protection measures; in addition, the smelting method of quartz ampoule bottle swinging horizontally results in uneven stirring, which makes it difficult to ensure the optical uniformity and infrared transmittance of the glass; the size of the quartz ampoule bottle itself The limitation is also difficult to realize the preparation of large-scale chalcogenide glasses

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] like figure 1 As shown, the chalcogenide glass preparation device for preparing large-sized chalcogenide glass in this embodiment includes a furnace body 1 and a central console 10 located outside the furnace body 1 for controlling the operation of various components. The furnace body includes a vacuum chamber 11 and An annealing furnace 12 with a side furnace door. There is a cooling chamber between the inner wall of the vacuum chamber and the outer wall of the vacuum chamber. Cooling water is poured into the cooling chamber. The water inlet valve of the cooling chamber and the drain valve of the cooling chamber are located On the outer wall, the water inlet valve of the cooling chamber is connected to the water outlet of the cooling water refrigeration device outside the furnace body, and the drain valve of the cooling chamber is conn...

Abstract

The invention relates to a production method of large-size chalcogenide glass. A chalcogenide glass production device used in the invention comprises a furnace body and a center console positioned outside the furnace body and used for controlling all parts to work, and the furnace body comprises a vacuum chamber and an annealing furnace with a side furnace door. After the working state parameters of all the parts of the chalcogenide glass production device are normal, a crucible on a crucible pushing rod is filled with a chalcogenide glass raw material which is prepared from germanium, antimony and selenium according to a preset molar percentage ratio, the temperature in the vacuum chamber, the temperature in the crucible and the rotating speed are adjusted in vacuum environment to fully and uniformly stir chalcogenide glass in a glassy state, and the size of a cooling die is adjusted to obtain the large-size chalcogenide glass product with high purity.

Description

technical field [0001] The invention relates to the field of preparation of chalcogenide glass, in particular to a preparation method of large-size chalcogenide glass. Background technique [0002] Chalcogenide glass is a binary or ternary compound glass formed by S, Se, Te and Ge, As, Sb and other elements according to the required ratio. Compared with other glasses, chalcogenide glass has a large refractive index (n=2.1~2.5), excellent infrared transmittance in a wide band (0.5μm~20μm), chemical stability and resistance to water and air corrosion Therefore, chalcogenide glass has been practically applied in the fields of infrared optics, optoelectronics and semiconductor materials, especially in the field of infrared thermal imaging technology and thermal imager, chalcogenide glass will present a wide range of application prospects. [0003] Since chalcogenide glass is easily oxidized at high temperature, especially active metals such as Ge and Ga are easily oxidized in t...
