  • Sintered boron carbide articles
    Patent number: 5720911
    Abstract: A method of making a boron carbide article by sintering includes mixing boron carbide with an epoxidized resin in solution and drying to form a granulated homogenized mixture and a carbonization cycle in which the mixture is maintained at at least two constant temperatures for predetermined times. The rates of temperature rise are at controlled rates sufficient to allow outgassing of the gases evolved during the decomposition of the resin.
