The sintered ceramic product comprises a granular material bound by a nitrogenous mold. According to the invention, at least one anti-dust agent selected among calcium and boron exists in a surface layer of the product, the mass ratio of all the anti-dust agents in the surface layer being greater than that measured underneath this layer. This product advantageously has a reduced ratio of non-adherent particles to its surface.
