The effects of Al and Ba on the colour performance of chromic oxide green pigment

open access: yesDyes and Pigments, 2009
On the basis of the novel hydrogen reduction of chromite ore, in activated sintering method was devised to prepare chromic oxide green pigment. Using XRD, SEM, EDX, ICP-AES, UV and reflectance colorimetry it was found that the colour performance of the ...

Hydrogen reduction: A novel method of synthesizing ultra-fine chromic oxide powder

open access: yesJournal Wuhan University of Technology, Materials Science Edition, 2010
The ultra-fine chromic oxide powder was prepared by a novel gas-solid reduction reaction. Na(2)CrO(4) was firstly reduced with hydrogen at 400-600 degrees C The obtained reduction products, mainly the mixture of NaCrO(2) and sodium hydroxide (NaOH), were
