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 devicesNickel Oxide Black
