Nickel Oxide ( NiO ) - Properties and Applications

Written by AZoMFeb 20 2004

Background

Nickel oxide ( NiO ) can be obtained as either a green or black crystalline powder.

Key Properties

Property	Value
Density (g/cm³)	6.67
Melting Point (°C)	1984

Applications

Nickel oxide has a range of applications such as:

For making electrical ceramics such as thermistors and varistors e.g. ferrites (nickel zinc ferrite)
Pigments for ceramic, glasses and glazes
Nickel oxide can be reacted with acids to form salts and other compounds e.g. nickel sulfamate for electroplating and nickel molybdate for hydrodesulfurisation catalysts
Gold doped nickel oxide films can be used as transparent electrodes in optoelectronic devices
