Abstract
Improvements made to the object of main patent no. 361,043, requested December 4, 1968 for "Improvements Introduced in the Manufacture of Calcined Refractory Bricks" containing below 1%, preferably below 0.5%, Fe2O3, showing a ratio of lime to silicic acid (weight ratio) of at least 1.65, preferably approximately 1.87, to 2.50, and are made up of more than 50% coarse grain of magnesia of at least 0.3 mm and less than 50% of grain fine magnesia of not more than 0.2mm, the coarse grain of magnesia consisting exclusively of magnesia with a ratio of lime to silicic acid of 1.70 to 5.0, preferably approximately 2.0, with at least 2% of fine grain of magnesia with a ratio of lime to silicic acid below 1.0 and containing the coarse grain of magnesia and also all the fine grain of magnesia below 1%, preferably below 0.5% Fe2O3, characterized by the addition of 1 to 8% alumina, based on the amount magnesia.
