What Is The Melting Point Of Nickel(II) Oxide?

The melting point of nickel(II) oxide, also known as nickel monoxide, is approximately 1984°C (3603°F). This value may vary slightly depending on the purity and preparation of the compound. It should be noted that nickel(II) oxide does not decompose upon melting, but rather undergoes a reversible phase transition from a rhombohedral crystal structure to a cubic crystal structure.
