Abstract

A refractory brick containing not more than 3% iron oxide calculated as Fe2O3, comprises by weight 70% to 97% of a substantially iron free periclase matrix containing at least 90% MgO, not more than 6% SiO2 and not more than 2% of any other single oxide, and embedded in this matrix from 3% to 30% of a magnesium silicate of minus 3 plus 28 Tyler mesh size containing not more than 15% iron oxide calculated as Fe2O3 and selected from the group of serpentine and magnesium orthosilicates. The serpentine may be raw or calcined and the magnesium silicate may also be added as fonsterite or olivine. The composition of the periclase specified is 91.7% MgO, 4.4% SiO2, 2.0% CaO, 0.9% Fe2O3, 1.0% Al2O3.ALSO:A refractory brick containing not more than 3% iron oxide calculated as Fe2O3, comprises by weight 70% to 97% of a substantially iron free periclase matrix which contains a minimum of 90% MgO, not more than 6% SiO2 not more than 2% of any other single oxide, and 3% to 30% of a magnesium silicate minus 3 plus 28 Tyler standard mesh size containing less than 15% iron oxide calculated as Fe2O3 and selected from the group consisting of magnesium orthosilicates and serpentine. The magnesium silicate may also be added as forsterite or olivine and the serpentine may be raw or calcined. The periclase specified has a composition of 91,7% MgO, 4,4% SiO2, 2,0% CaO, 0,9% Fe2O3, 1,0% Al2O3.
