Laboratorial Research for Low Cost Preparation of Nano Grade Tungsten Disulfide Particles

Abstract:

Developed a kind of ball milling device under ultrasonic energy field, which prepared out WS₂ particles with average particle size 59 nm, among which 85 percent particles are less than 100 nm. Get a group of suitable technical parameters, through contrastive experiments to milling time, milling balls size, mixing round speed, material plasma thickness, balls and material ratio and suchlike factors effect on powder preparation. The experiments result shows: effect of the experiment of balls milling with ultrasonic field is greatly better than that of the experiment balls milling without supersonic field; Furthers, inclined arrangement of ultrasonic breadth modulation bars gets better particles than vertical arrangement ultrasonic. This preparation method can get well and stable refining output with several times higher efficiency than other processing methods and then can meet the demands of nanograde WS₂ lot preparation in low cost.
