It has strong magnetism. Soluble in aqua regia and nitric acid. Although stable in dry air, it reacts rapidly in humid air, especially in the presence of CO2. Reacts with chlorine gas when hot. When hot with water vapor, nickel oxide and boric acid are formed.

Usage: Nickel boride was originally used as a catalyst for various reactions in hydrogen atmosphere, and has been used as a reaction and catalyst in many reactions, the advantages of nickel boride are mainly high hardness, good catalytic effect, high chemical stability and thermal stability in liquid phase reaction has good selectivity and reactivity, can be used as non-precious metal hydrogen electrode catalyst, fuel cell trap electrode catalyst.
