Abstract

The invention discloses a preparation device of gallium-containing chalcogenide glass having a high melting point and a high boiling point, and a preparation method thereof. The preparation device comprises a resistive heating system, an instant heating furnace, and an H-shaped quartz ampoule, wherein the resistive heating system has a temperature controller; the instant heating furnace can rapidly heat a glass raw material tube and a connection tube; the H-shaped quartz ampoule comprises the glass raw material tube and a purification glass tube; the glass raw material tube is communicated with the purification glass tube through the connection tube; and the upper end opening of the glass raw material tube is connected with a vacuum pump. The preparation device has the following advantage: the heating system can instantly heat the glass raw material tube and the connection tube to 1400DEG C to rapidly gasify a glass raw material in the glass raw material tube, the gasified glass raw material is distilled to the purification glass tube by going through the connection tube, and impurities are residual in the glass raw material tube because of high melting points, so the gallium-containing chalcogenide glass with low impurity contents is obtained.

Description

technical field

[0001] The invention relates to a preparation device and a preparation method of a high melting and boiling point chalcogenide glass, in particular to a preparation device and a preparation method of a gallium-containing high melting and boiling point chalcogenide glass. Background technique

[0002] Chalcogenide glass is a non-oxide glass with good chemical stability, high refractive index and very wide infrared transmission window. Taking advantage of its excellent far-infrared transmission ability, chalcogenide glass can be applied in the fields of infrared biochemical sensing technology, infrared exploration technology and infrared energy transmission.

[0003] However, the infrared transmittance of chalcogenide glass is easily affected by impurities inside the glass. There are oxide absorption bands of various metals or chalcogenide glass elements above the wavelength of 6 μm, especially the chalcogenide glass containing gallium at 15-20 μm There are la...
