Abstract
Process for the production of calcined refractory bricks based on magnesia as the main component, especially based on magnesia with more than 90% by weight of it and less than 2% by weight of Fe2O3, with an additive of a material rich in oxide of zirconium in a granulation up to 5 mm, the portion of size less than 1 mm at most being 50% by weight of the amount of additive, for example in the granulation of 0.2 to 5 mm, preferably from 1 to 5 mm, characterized in that the additive is unevenly distributed along the length of the brick, but with accumulation next to one end of the brick.
