Chromium oxide powder
The invention relates to a particulate powder, said powder having a median circularity of greater than 0.87 wt % and less than 9.0 wt % of particles having a size greater than 100 μm. The powder and at least 80 wt % of the particles have a chemical composition in wt % on the basis of the oxides and for a total of 100%: Cr2O3+Al2O3+ZrO2+MgO+Fe2O3+SiO2+TiO2≧90%; Cr2O3+Al2O3+MgO≧60%; Cr2O3≧9%; 20%≧SiO2≧0.5%; and other oxides: ≰10%. The invention can be used for a glass furnace.
