Embodiment 1

[0066] Example 1: 3mm diameter As 2 Se 3 Preparation of Chalcogenide Glass Spheroids.

[0067] In this embodiment, As 2 Se 3 Chalcogenide glass, the glass transition temperature is 185°C, and the inner diameter of the crucible outlet is 2mm. The barometer displays the relative air pressure. When the air pressure indication is zero, it means the ambient atmospheric pressure; when the barometer (1.6) shows a negative number, it means it is less than the ambient atmospheric pressure; ambient atmospheric pressure.

[0068] The ball blank preparation method comprises the following steps:

[0069] (1) Seal the discharge port with a discharge plug, and then As 2 Se 3 Put the chalcogenide glass block material into the quartz crucible through the feed port, and then use the feed plug to seal the feed port; (2) close the inlet valve, open the exhaust valve, and pump the quartz crucible until the air pressure is expressed as -10kPa, then close the pumping valve, then open the int...

Embodiment 2

[0070] Example 2: Ge with a diameter of 10mm 10 As 40 Se 50 Preparation of Chalcogenide Glass Spheroids.

[0071] In this embodiment, the Ge produced by China Academy of Building Materials Research Co., Ltd. is selected. 10 As 40 Se 50 Chalcogenide glass, the glass transition temperature is 225°C, and the inner diameter of the crucible outlet is 6.8mm. The barometer displays the relative air pressure. When the air pressure indication is zero, it means the ambient atmospheric pressure; when the barometer (1.6) shows a negative number, it means it is less than the ambient atmospheric pressure; ambient atmospheric pressure.

[0072] The ball blank preparation method comprises the following steps:

[0073] (1) Seal the discharge port with a discharge plug, and then place Ge 10 As 40 Se 50 Put the chalcogenide glass block material into the quartz crucible through the feed port, and then use the feed plug to seal the feed port; (2) close the inlet valve, open the exhaust v...

Embodiment 3

[0074] Example 3: Ge with a diameter of 20mm 28 Sb 12 Se 60 Preparation of Chalcogenide Glass Spheroids.

[0075] In this embodiment, the Ge produced by Hubei New Huaguang Information Materials Co., Ltd. 28 Sb 12 Se 60 Chalcogenide glass, the glass transition temperature is 285°C, and the diameter of the outlet of the crucible is 13mm. The barometer displays the relative air pressure. When the barometric pressure is zero, it means the ambient atmospheric pressure. When the barometer (1.6) shows a negative number, it means it is less than the ambient atmospheric pressure; when the barometer (1.6) shows a positive number, it means it is greater than ambient atmospheric pressure.

[0076] The ball blank preparation method comprises the following steps:

[0077] (1) Seal the discharge port with a discharge plug, and then place Ge 28 Sb 12 Se 60 Put the chalcogenide glass block material into the quartz crucible through the feed port, and then use the feed plug to seal the...

Abstract

The invention discloses a preparation device of a chalcogenide glass ball blank, and a using method thereof. The device comprises a charging system, a heating furnace, a ball blank collecting system and a fixing support. The charging system comprises a quartz crucible, an extraction valve, an air inlet valve, a feeding plug, a discharging plug, a barometer and a gas flow meter. The upper part of the quartz crucible is provided with an extraction opening, a feeding opening, an air inlet and an air pressure meter interface, and the bottom is provided with a discharging opening. The ball blank collecting system comprises a magnetic stirrer, magnetons, a container and silicone oil. The charging system is embedded in the heating furnace, the ball blank collecting system is located under the charging system, and the charging system and the heating furnace are fixed to the fixing support. The chalcogenide glass ball blank with the diameter of 3-20 mm can be prepared, the material utilization rate can reach 90% or above, the surface of the ball blank is smooth, few materials are worn in post-processing, and the processing cost is low.

Description

technical field [0001] The invention relates to a glass spheroid preparation device, in particular to a preparation device and a use method of a chalcogenide glass spheroid. Background technique [0002] Infrared thermal imaging system has been widely used in industrial manufacturing, building detection, power detection, fire protection, security, vehicle night vision and other fields. It uses the temperature difference (or radiation difference) between the target and the background or each part of the target to detect the target and identification. Its working principle is: the infrared radiation of the target object passes through the atmosphere and reaches the infrared optical system. The infrared image required by the system is obtained through linear correction and image processing, and is provided by the display system for the user to observe. [0003] In an infrared thermal imaging system, an infrared lens is a key component of its optical system. Commonly used inf...
