Document Type and Number:
WIPO Patent Application WO/2018/230438
Kind Code:
A1
Abstract:
Provided are: a black mixed oxide material which does not contain chromium per se of any valency as a main component, dose not contain cobalt as a main component too, has a high safety and good color tone and is economically advantageous; and a method for manufacturing the same. Also provided are various products using the black mixed oxide material. The mixed oxides comprise oxides containing La, Mn and Cu as main components but containing neither Cr nor Co as a main component, wherein the contents of La, Mn and Cu in the mixed oxides satisfy the following ratios, each in terms of oxide relative to the weight of the total mixed oxides (100 wt%): the La content as La2O3 being 35-70 wt%; the Mn content as MnO2 being 25-60 wt%; and the Cu content as CuO being 0.5-10 wt%.
