  • Carbon bonded refractory brick composition
    Patent number: 4210453
    Abstract: A composition for molding refractory bricks having improved stability and load resistance in a furnace at elevated temperatures includes between 50 to 97 percent by weight of a pulverulent sized refractory material and between 3 to 27 percent by weight carbon. The carbon in the composition before curing at elevated temperatures includes a liquid carbonaceous bonding resin which improves the moldability of the composition before curing and provides high strength and rigidity to the brick after curing at elevated temperatures.
