Pyrophyllite brick is a kind of burnt brick made from raw material mostly consist of high silicon pyrophyllite.It has certain thermal expansivity during service so that the integrity is well. In addition it is also featured by good temperature shock stability, viscous slag resistant, so that it is a suitable brick laying material for the permanent refractory layer of ladles, tundishes and torpedo metal mixers.The high silicon pyrophyllite brick(PY83) is a kind of burnt brick made from raw material mostly consist of  well selected high silicon pyrophyllite. In addition to the advantage of the pyrophyllite brick, it is also featured by high erosion resistance, no pollution to molten steel and slagging resistance, no pollution to molten steel and slagging resistance. It is the ideal material for laying the working layer of the ladles on the small size electric furnace.
