What is Nickel oxides used for?
Nickel oxide has a variety of professional applications. Usually, it is used to distinguish between "chemical grade" and "metallurgical grade". "Chemical grade" is a relatively pure material used for special applications, while "metallurgical grade" is mainly used to produce alloys. Used in the ceramic industry to manufacture glass powder, ferrite and enamel. The sintered oxide is used to produce nickel steel alloys. Charles Edouard Guillaume (CharlesÉdouard Guillaume) won the 1920 Nobel Prize in Physics for his research on nickel-steel alloys, which he called Invar and Invar. 
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 is a commonly used hole transport material in thin-film solar cells. It is also a component of nickel-iron batteries (also known as Edison batteries) and a component of fuel cells. It is the precursor of many nickel salts, used as specialty chemicals and catalysts. Recently, until the development of environmentally friendly NiMH batteries, Nickel oxide was used to manufacture NiCd rechargeable batteries used in many electronic devices. 
Is nickel oxide toxic?
CLINICAL FEATURES: ACUTE EXPOSURE Although nickel oxide is a pulmonary irritant, acute exposure is unlikely to result in significant poisoning. Documented clinical cases invariably involve chronic occupational inhalation.
Nickel oxide is an anode electrochromic material and has been extensively studied as a counter electrode of tungsten oxide and cathode electrochromic material in complementary electrochromic devices.
Nickel oxide is used as a binder and colorant for enamel in the pusher industry.
The ceramic industry is used as a raw material for colorants.
Used as a raw material for nickel-zinc ferrite in the production of magnetic materials.
Colorant for stained glass and tubular glass bulbs in the glass industry.
It is also a material used to manufacture nickel salts, nickel catalysts and secondary batteries.
Nickel oxide can react with acids to form salts and other compounds, such as nickel oxide. Nickel sulfamate for electroplating and nickel molybdate for hydrodesulfurization catalyst
Gold-doped nickel oxide films can be used as transparent electrodes in optoelectronic devices.
