Ball-milling processing of nanocrystalline nickel

2007-7-4 · The planetary ball milling (PBM) has been used to process the nanocrystalline nickel hydroxide powder, which was synthesized by a chemical precipitation method. It is found that the PBM processing can significantly break up the agglomeration, uniformize the particle size distribution, and increase the surface area of nanocrystalline β-Ni(OH) 2 particles.

The effect of trace nickel additive and ball milling

2012-9-1 · Sol spray drying is used to prepare ultrafine W powder with 0.1wt.%Ni additive. Ball milling is adopted to further activate ultrafine W–0.1Ni composite powder. Trace nickel in joint with ball milling greatly improve the sinterability of W. W–0.1Ni powder ball milled for 5 h can be sintered to 99.4%TD at 1600 °C. Microstructure evolution during sintering is investigated in detail.

Nickel phosphide: the effect of phosphorus content

Surface Ni and P atoms in nickel phosphide might undergo reorientation during the course of the ball milling process due to the local heat generated by colliding balls and subsequent annealing resulting in a homogenous, more amorphous Ni 2 P surface as opposed to the starting compounds as discussed earlier. It has to be noted here that nickel phosphide does not undergo any bulk structural change over the course of ball milling
