The application in Glass Industry Of Nickel Oxide

Sincere Union Imp&Exp Co.,Ltd (Metals Kingdom Industry Limited )supply all kinds of nickel oxide(nickle oxide) The impurities in nickel compound is ferric oxide (FeO)whose content is from 0.1%-2.0%.The presence of iron is harmless for manufacturing glass and quartz glass, but nickel oxide with the lowest content must be used when preparing the high quality glass(wood glass) ,which plays as the materials of UV filter. The reason using the lowest content nickel oxide is that iron oxide can reduce spectral the transmittance out of ultraviolet light.

Using nickel color has a certain range, namely, it is used to obtain a smoky- grey tone and to make potassium lead crystal glass decolorize. According to the special range, the ultraviolet light transparent glass, the grey glass, the gray screen glass used in black-white and color picture tube, and solar protection glass will be pointed out. Nickel element has good reproducibility because of its stability of oxidation state in the glass liquid, and it has nothing with the melting conditions.
