Abstract
A device selected from among a glass furnace and a channel for dispensing the glass comprising a block and/or a coating made of a sintered material obtained by sintering a particular mixture comprising a chromium oxide content, indicated as 'CrT', of between 10% and 82%. The die fraction is such that 0.39·(CrT)+24<CrM<0.39·(CrT)+52, CrM denoting the chromium oxide content by weight of the die fraction in wt % on the basis of the oxides of the die, and the aggregate is such that xII≧97%, xIII≧70%, and xIV≦xIII−70%, CrG denoting the chromium oxide content by weight of one grain in wt % on the basis of the oxides of said grain.
