Claim Text:
1. Sintered product having an average chemical composition such that, in percentages by weight on the basis of the oxides: Cr 0.5%≦TiO 0.15%≦MgO≦3.0% ZrO provided that the TiO 2 /MgO molar ratio is between 1.5 and 9.0 and the TiO 2 /Cr 2 O 3 molar ratio is less than 0.12, the sintered product comprising less than 2.0%, by weight on the basis of the oxides, of oxides other than Cr 2 O 3 , TiO 2 , MgO, and ZrO 2 .
