1. Способ получения никеля шарообразной формы, включающий его осаждение из сульфат-хлоридного электролита на электропроводные участки катодной основы, покрытой диэлектриком, каждый из которых имеет площадь не более 0,5 см2 катодного тока во время периода осаждения t, отличающийся тем, что осаждение проводят на участки, имеющие форму правильной пирамиды, при первоначальной плотности катодного тока 0,6-0,8 А дм2, которую затем изменяют следующим образом: от 0 до 1/4 t поддерживают постоянной; от 1/4 t до 1/2 t увеличивают не более, чем на 0,01 А дм2•r-1; от 1/2t до 3/4 t поддерживают постоянной; при 3/4 t увеличивают на 1,5-3,0 А/дм2; от 3/4 t до t поддерживают постоянной.1. A method for producing spherical nickel, including its deposition from a sulfate chloride electrolyte on electrically conductive sections of a cathode base coated with a dielectric, each of which has an area of not more than 0.5 cm 2 of cathode current during the deposition period t, characterized in that the deposition carried out in areas having the shape of a regular pyramid, with an initial cathode current density of 0.6-0.8 A dm 2 , which is then changed as follows: from 0 to 1/4 t keep constant; from 1/4 t to 1/2 t increase by no more than 0.01 A dm 2 • r -1 ; from 1 / 2t to 3/4 t keep constant; at 3/4 t increase by 1.5-3.0 A / dm 2 ; 3/4 t to t is kept constant. 2. Способ по п. 1, отличающийся тем, что осаждение проводят на катодную основу, представляющую собой одну или несколько соединенных между собой правильных пирамид с электропроводными участками вблизи вершин, которую вращают с частотой 0,5-2,0 мин-1.2. The method according to p. 1, characterized in that the deposition is carried out on a cathode base, which is one or more interconnected regular pyramids with electrically conductive sections near the peaks, which is rotated with a frequency of 0.5-2.0 min -1 .
