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.
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
4 ↔ 2NaH + B
- 3Ni + 2B
6 + NaH ↔ Ni
3B + 3BH
3 + 2H
2 + Na
but other reactions occur, yielding other borides.
