Preparation method of cuprous telluride powder and target material
The invention belongs to the field of material preparation, and discloses a preparation method of cuprous telluride powder and a target material. The preparation method of the cuprous telluride powder comprises the following steps that tellurium powder and copper powder are mixed, heating reaction is carried out in the hydrogen atmosphere at the temperature of 350-400 DEG C, and the cuprous telluride powder is obtained. Cuprous telluride powder is used as a raw material for a heating reaction, and a cuprous telluride target material is obtained; the heating mode of the heating reaction is as follows: under a vacuum condition, the temperature is raised to 600-650 DEG C, and the temperature is kept for 90-120 minutes; and after the temperature is increased to the highest temperature, the pressure is increased to 60-70 Mpa, and the pressure is maintained until the heat preservation time is over. The cuprous telluride powder is prepared by adopting a tubular furnace low-temperature powder synthesis method, mass production can be realized, the requirement on equipment is low, the cuprous telluride target material is prepared by adopting vacuum hot pressing sintering, the process flow is short, the operation is simple and convenient, and the obtained cuprous telluride target material is low in oxygen content and high in relative density.
本发明属于材料制备领域，公开了一种碲化亚铜粉末及靶材的制备方法。碲化亚铜粉末的制备方法包括以下步骤：将碲粉和铜粉混合，在氢气氛围、温度为350~400℃的条件下进行加热反应，得到碲化亚铜粉末。以碲化亚铜粉末为原料进行加热反应，得到碲化亚铜靶材；所述加热反应的加热方式为：真空条件下，升温600~650℃，保温90~120min；在升温到最高温度后开始加压至60~70Mpa，并保压至保温时间结束。本发明采用管式炉低温粉末合成法制备碲化亚铜粉末，可以大批量生产，对设备要求低，采用真空热压烧结制备碲化亚铜靶材，工艺流程短，操作简便，所得碲化亚铜靶材的氧含量低，靶材相对密度高。
