Problems solved by technology

Although this method can successfully prepare antimony powder, the main disadvantage is that a small amount of antimony dissolved in the anode is still hydrolyzed into antimony oxychloride in a high-concentration hydrochloric acid solution, and a small amount of antimony oxide is precipitated at the cathode, so the antimony powder prepared by this method has a high purity not tall

Abstract

The invention provides a method for preparing antimony powder. Add metal antimony salt and N,N-dimethylformamide (DMF) in sequence to a hydrothermal reaction kettle, react at a temperature of 120-200°C for 4-24h, and filter the precipitate After washing, dry in a vacuum oven for 6 hours to obtain the product antimony powder. The preparation method of the present invention solves the problems of high energy consumption, wide distribution range of antimony powder and low purity in the method for preparing antimony powder in the prior art. Antimony powder is prepared by reducing metal antimony salt with DMF, with simple method and raw materials Micron antimony powder with uniform particle size distribution is prepared. The steps are simple, the operation is convenient and the practicability is strong.

Description

technical field [0001] The invention belongs to the field of inorganic functional materials, in particular to a method for preparing metal antimony powder. Background technique [0002] So far, according to the published antimony powder preparation patents and literature, there are mainly three methods for the preparation of antimony powder. One is to heat and liquefy pure metal antimony, and then atomize liquid metal antimony under the condition of inert atmosphere. This method is a commonly used method for preparing metal powder, but the main disadvantage of this method is that the prepared antimony powder has a particle size of The distribution range is wider and the energy consumption is higher. Such as: Gong Wen has announced a kind of antimony powder conversion furnace in the public information that application number is: 201320373291.X. The second is the method of ball milling. This method is to mix the primary crushed antimony powder with liquid additives, and the...
