Preparation method for transition metal pnictide powder by reaction milling

摘要

The present invention is a titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel-phosphorus and the transition metal powder, such as (Ni) and copper (Cu) ( P) and arsenic (transition to the Group VB reaction by elemental powder reaction milling method such as as), to a method for producing a metal Nick Tide (pnictide) powder.; According to the present invention, a transition metal powder and a VB group element powder 0.5: the method comprising: mixing, in atomic ratio of 1;: 1-4 In the steps of the reaction vessel with the mixture and diameter 5 ~ 30 mm and the ball; The step of filling the argon (Ar) to the reaction vessel and; Proposes a method of manufacturing a transition metal Nick Tide Powder by reaction mill comprising a heat treatment step of the reaction the powder for removing the stresses and defects inside the powder as required for addition to the mixture of high-energy ball milling.; Accordingly, the invention is a transition metal powder and the transition metal Nick Tide powder as a raw material, a VB group element and the powder milled to this reaction can be prepared in a short period of time at room temperature.
