Abstract
Process for the manufacture of calcined or non-calcined refractory bricks or of refractory masses, based on magnesia, adding to a magnesia component zirconium dioxide or a zirconium compound that when calcined supplies at least 90% by weight of ZrO2, and The obtained magnesia material is subsequently transformed, optionally after adding a quantity of chromium ore or sintered magnesia and chromium of up to 50% by weight of the total mixture, into fired bricks, eventually impregnated with a high carbon carrier carbon content, or in uncooked bricks chemically bonded or with tar or fish, or also in refractory masses, characterized in that the magnesia component is used with contents not higher than 0.7% by weight of SiO2, maximum 6% by weight, preferably not more than 4% by weight of CaO, not less than 3% by weight of R2O3 and not less than 2% by weight of Fe2O3, in all cases referring to a quantity of the magnesia component, and with a weight ratio of lime-silicic acid of not less than 1.87, and because zirconium dioxide or the other zirconium compound is added in at least such an amount that up to combine in the form of calcium zirconate the amount of CaO necessary per se for the formation of dicalcium ferrite corresponding to the content of R2O3 and other CaO-R2-O3 compounds, as well as in any case a free amount of CaO .
