Nd2Fe14B particles were obtained from mixture of neodymium oxide, iron oxide, boric acid and CaH2 by reduction-diffusion process. Two different washing processes were used for the separation of magnetic particles from Ca and CaO matrix: usual washing with water and planetary ball milling process in ethanol media. Nd2Fe14BHx hydrogenated state was formed after usual washing with water.

Ball milling of calcium carbide (CaC 2) enables the reaction of its ethynyl moiety with organic electrophiles.This was realized simply by co-milling CaC 2 with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing α-hydrogens were ethynylated in good yields at short reaction times.

The ball mill was loaded with 10:1 (mass ratio) for the ball (10 mm ϕ) and the sample. To avoid the generation of high temperature from high-speed ball mill, the milling time was set to 2-min working with 7-min breaks. To determine the effect of the ball-milling time, the total duration of milling process varies from 100 to 4000 min.
