Trinickel boride is a compound of
nickel and
boron with
chemical formula Ni
3B. It is one of the
borides of nickel.
The compound was described in 1959 by R. Fruchart, [2] S. Rundquist, [3] and L. H. Anderson and R. Kiessling. [4] It is a hard solid with the cementite crystal structure. [5]
Trinickel boride can be obtained, as grains embedded in a nickel matrix, by heating Brown's P-1 and P-2 "nickel boride"catalyst to 250 °C. This catalyst is produced by reduction of nickel salts with sodium borohydride. [5]
Trinickel boride can be obtained also by compressing nickel and boron powders with explosives. [6]
Recently it has been found that Ni
3B can be formed (together with other nickel borides) by heating sodium borohydride with powdered nickel metal to 670 °C in a closed vessel, so that the released
hydrogen creates a pressure of up to 3.4
MPa. The main reactions can be summarized as
but other reactions occur, yielding other borides. [7]
