Method and Process for Manufacturing Chalcogenide Glass.
Introduction.
Chalcogenide glasses, also known as chalcogenides, are
a class of inorganic non-oxide glasses that exhibit unique optical, electrical, and thermal properties. They are composed of chalcogen elements, such as sulfur (S),
selenium (Se), and tellurium (Te), combined with other elements like arsenic (As), germanium (Ge), and antimony (Sb). Chalcogenide glasses have a wide range of applications, including optics, photonics, electronics, and energy storage.
Method of Manufacturing.
The manufacturing process of chalcogenide glass
involves several steps:
1. Raw Material Preparation: The raw materials, which are typically elemental chalcogens and other elements, are purified and weighed according to the desired composition.
2. Melting: The raw materials are loaded into a
crucible and heated to a high temperature, typically above 800°C, in a controlled atmosphere. The molten mixture is held at this temperature for a sufficient time to ensure complete homogenization.
3. Annealing: The molten glass is then slowly cooled to room temperature to relieve any internal stresses. This process is known as annealing and is critical for producing a stable and durable glass.
4. Forming: The annealed glass can be formed into various shapes using techniques such as casting, molding, or extrusion. The forming process involves shaping the molten or softened glass into the desired geometry.
5. Post-Processing: After forming, the glass may
undergo additional post-processing steps, such as grinding, polishing, or coating, to achieve the required surface quality or optical properties.
Process Flowchart.
The process flowchart for manufacturing chalcogenide glass can be summarized as follows:
Raw Material Preparation → Melting → Annealing → Forming → Post-Processing.

硫系玻璃加工方法及流程。

简介。

硫系玻璃，又称硫族化物玻璃，是一类具有独特光学、电学和
热学性质的无机非氧化物玻璃。

它们由硫（S）、硒（Se）和碲（Te）等硫族元素与砷（As）、锗（Ge）和锑（Sb）等其他元素结合而成。

硫系玻璃具有广泛的应用，包括光学、光子学、电子学和能量储存领域。

加工方法。

硫系玻璃的加工工艺包含以下几个步骤：
1. 原料制备，将原材料（通常为元素硫族元素和其他元素）进行提纯和称量，按照所需的成分配比。

2. 熔化，将原材料装入坩埚中，在受控气氛下加热至高温（通常高于800°C）。

将熔融混合物在此温度下保持足够的时间，以确保完全均质化。

3. 退火，然后将熔融玻璃缓慢冷却至室温，以消除任何内部应力。

这个过程称为退火，对于生产稳定且耐用的玻璃至关重要。

4. 成型，退火的玻璃可以通过浇铸、模压或挤压等技术成形为各种形状。

成型过程涉及将熔融或软化的玻璃塑造成所需的几何形状。

5. 后处理，成型后，玻璃可能需要额外的后处理步骤，例如研
磨、抛光或涂层，以达到所需的表面质量或光学性能。
