摘要

the present invention relates to a process for the production of a sintered magnesium oxide granulation, the sintered magnesium oxide of which is produced by sintering pressed articles, in particular, pellets made of mgo powder, preferably powder caustic of mgo, and then mechanical crushing of the pressed articles, being that it is sintered in such a way that the granulation presents a grain porosity (total porosity) of 15 to 38% in volume, preferably of 20 to 38% in volume of according to din en 993-1: 1195-04 and din en 993-18: 1999-01, as well as a mixture for the production of a molded or unmolded fire resistant crude ceramic product containing oxide of sintered magnesium, a product of that type manufactured from that mixture, as well as a process for its production, a coating, in particular, a working lining or one of an industrial oven, the coating in particular being a lining of work and / or an alven The rear aria of a high-volume industrial oven has at least one product of this type as well as an industrial oven of that type.
