Preparation device and preparation method of cadmium selenide powder and preparation method of cadmium selenide target material
The invention belongs to the field of material preparation, and discloses a preparation device and a preparation method of cadmium selenide powder and a preparation method of a cadmium selenide target material. The preparation device comprises a reactor, the reactor comprises a heating reaction cavity and a cooling cavity, the heating reaction cavity comprises a first heating cavity, a second heating cavity and a reaction cavity, the first heating cavity and the second heating cavity are arranged at the two ends, the reaction cavity is arranged between the first heating cavity and the second heating cavity, and the lower portion of the reaction cavity is communicated with one end of the cooling cavity; the preparation method comprises the following steps: respectively filling Cd powder and Se powder into a first heating cavity and a second heating cavity, respectively heating the Cd powder and the Se powder to 800-850 DEG C and 750-800 DEG C to generate cadmium selenide powder, and collecting the cadmium selenide powder by a cooling cavity; and carrying out heating reaction on the cadmium selenide powder to obtain the cadmium selenide target material. The preparation device is simple in structure, is matched with a preparation process of cadmium selenide powder, is short in process flow, is simple and convenient to operate, and is suitable for large-scale production and preparation of cadmium selenide and target materials thereof which are low in oxygen content and do not need post-treatment.
本发明属于材料制备领域，公开了一种硒化镉粉末的制备装置及制备方法、及硒化镉靶材的制备方法。制备装置包括反应器，反应器包括加热反应腔和冷却腔，加热反应腔包括设置在两端的第一加热腔和第二加热腔、设置在第一加热腔和第二加热腔之间的反应腔，反应腔的下方与冷却腔一端连通；制备方法包括以下步骤：将Cd粉和Se粉分别装入第一加热腔和第二加热腔中分别升温至800～850℃、750～800℃，生成硒化镉粉末，由冷却腔收集；硒化镉粉末进行加热反应，得到硒化镉靶材。本发明的制备装置结构简单，配合硒化镉粉末的制备工艺，工艺流程短、操作简便，适用于大规模生产，制备低氧含量、且无需后处理的硒化镉及其靶材。
