Application for Nickel Oxide Metals Kingdom Industry Limited The UV lamp glass for Wood Ceramic and GlassItalic text Nickel oxide is light green or black powder, so it first used for glaze formulation of ceramic colored,while, nickel oxide can change color because of oxidation in the process of Calcination, so with a high content of nickel oxide glaze porcelain will change in the sintering process, and is difficult to achieve the desired color.Besides,for increasing the affinity between the metal surface and the glaze,NiO also be used in the producing of enamel. Adding NiO make glass change color,at the same time, change the structure and properties of glass, weaken the glass absorption on the UV and increase the glass absorption on the visible light, such as Wood glass used to manufacturing filtration UV lamps commonly, that is to say when we adding nickel oxide 9% in barium glass, visible light could be absorded and emit light almost are long wave with 320-400 nm wavelength, which can be used to check fungal infect.

Catalytic AgentItalic text

NiO can be used as catalytic agent. Because it is a non stoichiometric compound,so the surface of NiO has excess +2 nickel ion or trivalent nickelion that NiO can attract various oxygen anion such as O-,O2- and O22-,which will be urged to stay at the suface of NiO for reacting with CO or organic hydrocarbon gas,and as result, make the oxidation process of CO or other organic compounds such as CH4 accelerate.

Battery and Semiconductor DeviceItalic text In1901,Edison used NiO as cathode,iron as anode,develop the nickel iron battery.When nickel iron battery began to discover,NiO was used as an electrode,but because of the badly low temperature performance and the high manufacturing cost,it is gradually replaced by lithium battery now.During recent years, semiconductor-P of NiO begin to draw the attention of researcjers.After NiO adsorption gas or electric field,the number of nickel ion staying at its suface that change the conductivity and color of NiO.Above all,NiO can be used in the manufacture of resistance type semiconductor gas sensors and electrochromic devices.
