| titleOfInvention | Method for preparing amorphous boron powder |
| abstract | Provided is a method for preparing the amorphous boron powder, comprising uniformly mixing a reducing agent, a boron-containing compound, and an alkali metal compound-containing molten salt which have the mass ratio of 1.0:(1.2-3.6):(0.2-16.0), performing thermal treatment on same for 0.5-8 h at the temperature of 600-1,300ºC in a protective atmosphere, resolving a thermal treatment product with water or the alkali solution at the temperature of 195-250ºC, filtering same, washing same, and drying same to prepare the amorphous boron powder. The method is low in production costs, is environment-friendly, is easily applied to industrial production, makes it possible to recycle a reaction byproduct, and has a high recovery rate of boron. The amorphous boron powder prepared by the method has a small particle size, a narrow granularity distribution, and a high purity. |
