Dinickel boride is a
chemical compound of
nickel and
boron with
formula Ni
2B.
[1]
[2] It is one of the
borides of nickel.
The formula "Ni
2B" and the name "nickel boride" are often used for a
nickel-boron catalyst obtained by reacting nickel
salts with
sodium borohydride. However, that product is not a well-defined compound, and its bulk formula is closer to Na
2.5B(sic).
[3]
Dinickel boride can be obtained (together with other nickel borides) by heating sodium borohydride with powdered nickel metal up 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. [4]
