Effect of ligand nature on composition of solids reduction product of nickel complexes with borohydride in aqueous solution

It is shown that boron content in a solid product of Ni2 reduction with borohydride may vary from 17.9 up to 37.5 at. %, depending on ligand nature, introduced additions and pH. The character of crystallization processes proceeding during Ni-B powder heating is dependent not only on the quantity of cooprecipitation boron, but also on additions availability in solution, in particular surface-active substances influencing the character of reduction product
