Product made of dense silicon carbide
The invention relates to a sintered product having a relative density higher than 97%, and consisting of: more than 92% by weight of silicon carbide; between 0.5 and 8% by weight of a secondary amorphous phase comprising the elements O, Si and one or both elements chosen from Al and Y; and at least 2% of other elements, present in said product in the form of an additional phase or as inevitable impurities, in which, the silicon carbide is present in the form of crystallised grains and in which said secondary phase is amorphous and essentially located at the silicon carbide grain boundaries.
