The surface of superfine boron powder was coated with lithium fluoride prepared by reacting LiOH with HF by the neutral precipitation method. The effect of the concentration of LiOH solution on the coating effectiveness of superfine boron particles was studied. Transmission Electron Microscope, rotary viscometer and X-ray photoelectron spectroscopy were used to analyze the coating effectiveness of boron particles coated with LiF. The results show that the film on the boron particles is well distributed and ...
