Abstract
1. Способ получения твердого раствора наноразмерного порошка железо-кобальт, включающий приготовление раствора солей гептагидрата сульфата железа и гексагидрата хлорида кобальта, его нагрев, осаждение щелочью солей металлов в виде гидроксидов железа и кобальта при непрерывном перемешивании, отличающийся тем, что в ходе перемешивания для осаждения гидроксидов железа и кобальта в раствор вводят 20-25 г твердой щелочи сухого гидроксида натрия, после чего в раствор добавляют 20-40 мл раствора 65 мас.% гидразин гидрата и выдерживают в течение 5-20 мин. ! 2. Способ по п.1, отличающийся тем, что раствор солей железа и кобальта нагревают до 80-90°С перед осаждением гидроксидов. ! 3. Способ по п.1, отличающийся тем, что растворы солей железа и кобальта готовят в следующем соотношении, мас.%: соль железа 70-30, соль кобальта 30-70. 1. The method of obtaining a solid solution of nanoscale iron-cobalt powder, including the preparation of a solution of salts of iron sulfate heptahydrate and cobalt chloride hexahydrate, its alkali precipitation of metal salts in the form of iron and cobalt hydroxides with continuous stirring, characterized in that during stirring, for precipitation of iron and cobalt hydroxides, 20-25 g of solid alkali of dry sodium hydroxide are added to the solution, after which 20-40 ml of a solution of 65 wt.% hydrazine hydrate are added to the solution and kept for 5-20 m in. ! 2. The method according to claim 1, characterized in that the solution of iron and cobalt salts is heated to 80-90 ° C before precipitation of hydroxides. ! 3. The method according to claim 1, characterized in that the solutions of iron and cobalt salts are prepared in the following ratio, wt.%: Iron salt 70-30, cobalt salt 30-70.
