It is not a well characterised, sometimes referred to as black nickel oxide.

It decomposes at still higher temperatures to nickel oxide.

Nickel oxide can refer to either of these chemical compounds:

The clean methane is then reacted with steam over a catalyst of nickel oxide.

Wood's glass is special barium-sodium-silicate glass incorporating about 9% nickel oxide.

This normally makes a black nickel oxide.

It is prepared by the reaction of nickel oxide with nitric acid:

It uses nickel oxide hydroxide and metallic cadmium as electrodes.

This process converts nickel oxides into pure nickel.

It is also produced by dissolution of nickel metal or nickel oxides in sulfuric acid.

Chrysoprase (also spelled chrysophrase) is a green variety of chalcedony, which has been colored by nickel oxide.

The Ni-Cd battery contains cadmium and nickel oxide electrodes.

Nickel oxide may refer to:

Iron rust is nontoxic, preferable over mercury (element), cadmium, manganese and nickel oxides.

The remaining nickel sulphide is then oxidized to form nickel oxide by a roasting operation at approximately 1050°C.

In a recent update,147 risk was correlated more strongly with estimated cumulative exposure to soluble nickel than to nickel oxide.

Calcining (heating to drive off CO and water) of these carbonates gives nickel oxide:

Nickel mattes, nickel oxide sinters and other intermediate products of nickel metallurgy.

In a nickel-cadmium battery, the negative electrode is made of cadmium and the positive electrode of nickel oxide.

The nickel-metal/nickel-oxide structure is more active than pure nickel metal or pure nickel oxide alone.

In addition, a "black-pad" of nickel oxide would form during the immersion gold plating step, greatly reducing solder joint reliability.

Heating nickel oxide with either hydrogen, carbon, or carbon monoxide reduces it to metallic nickel.

Stainless steel fume has chromium oxide (CrO3) and Nickel Oxide in it.

In "cordless" appliances the rechargeable batteries use cadmium for an anode and nickel oxide for the cathode.

The nickel sulphide fraction is roasted in fluid bed roasters to produce a nickel oxide product suitable for the steel industry.
