text: A more preferred embodiment of this embodiment of the invention is an unburned magnesite refractory brick, formed from a mixture of from about 89% to about 92% by weight periclase containing at least 96%, but more preferably from about 96% to about 99% by weight MgO; from about 3.5% to about 6%, preferably 5.5%, by weight pitch with a minimum softening point of 90° C. (as tested by the cube in air method ASTM #D-2319); and from about 1% to about 8%, more preferably from about 3% to about 5% by weight steel fibers, low carbon steel fibers, or stainless steel fibers which are from 10 to 40 mm in length and from about 0.1 to about 1.0 mm in diameter.
text: More preferably, the mixture contains from about 89% by weight to about 92% by weight periclase containing at least about 96% by weight MgO, from about 3% to about 5% by weight steel fibers, about 35 mm in length and about 0.5 mm in diameter with an irregular cross-sectional shape, and about 5.5% by weight pitch.
