Nickel boride, English name is Nickel boride, CAS number is 12007-01-1, molecular formula is Ni2B, molecular weight is 69.51.Solid. Melting point 1020°C, relative density 7.3.

Strongly magnetic. Soluble in aqua regia and nitric acid. Stable in dry air, but in humidAir reacts rapidly, especially in the presence of CO2. When heated to a high temperature, it can react with chlorine gas.

When heated together with steam, it can generate nickel oxide and boric acid.It is an inorganic chemical raw material that should be stored sealed in a cool, dry place.
