Method for directly synthesizing high-purity bornite through solid-phase reaction
The invention discloses a method for directly synthesizing high-purity bornite through a solid-phase reaction. The method comprises the following steps: weighing analytically pure cuprous sulfide, copper sulfide and analytically pure ferrous sulfide according to a molar ratio of 2: 1: 1, and carrying out grinding and uniform mixing to obtain an initial raw material; pressing mixture powder into acylinder, covering the end face of the cylinder with a powdered sulfur wafer, filling platinum-graphite double sample cavities with the powdered sulfur wafer, the mixture cylinder and the powdered sulfur wafer in sequence, sealing the platinum-graphite double sample cavities to prepare a sample, and placing the sample in an h-BN pipe, wherein h-BN serves as a pressure transmission medium; and carrying out high-temperature and high-pressure reaction in a large cubic press, taking out the reacted cylindrical sample, carrying out grinding and polishing, then carrying out ultrasonic cleaning and air drying, and storing the cylindrical sample in an inert gas atmosphere. The obtained bornite is of a single phase and is free of impurities.
本发明公布了一种固相反应直接合成高纯度斑铜矿的方法，使用分析纯的硫化亚铜、硫化铜和分析纯的硫化亚铁按照摩尔比2:1:1称量，研磨混合均匀作为起始原料；将混合物粉末压成圆柱，端面用硫粉圆片盖住，按硫粉圆片‑混合物圆柱‑硫粉圆片顺序装入铂金‑石墨双样品腔密封制成样品，并置于h‑BN管中，以h‑BN为传压介质；在六面顶大压机进行高温高压反应，将反应后的圆柱样品取出，打磨抛光，超声清洗风干后放入惰性气体氛围保存。得到的斑铜矿为单一物相，无杂质。
