Beschreibung
Zusammenfassung:	The invention relates to a boron carbide composite material comprising diamond particles and boron carbide, the composite material having a porosity of less than 2 percent by volume. The invention further relates to a method for manufacturing such materials, the method including coating a plurality of diamond particles with boron carbide, combining the plurality of diamond particles to form a green body and subjecting the green body to a temperature in the range from about 1,200 degrees centigrade to about 2,000 degrees centigrade and pressure or vacuum not exceeding about 2,000 Mpa.
