The nominal boron carbide stoichiometric formula is B 4 C; however, it has a very wide phase stoichiometric range from B 4 C up to B 10.5 C. Boron carbide powder is produced commercially using either (1) fusion, which involves a reduction of boron anhydride (B 2 O 3) with carbon (endothermic); or (2) magnesiothermy, in which boron anhydride reacts with magnesium in the presence of carbon

2018-11-22 Boron carbide-reinforced copper metal matrix composites have been the subject of broad research because of their good mechanical, electrical and tribological properties. In the present research, Cu–B4C composites containing 5, 10 and 15 wt% of B4C have been fabricated by cold powder compaction followed by conventional sintering at 900 °C for 1 h under argon atmosphere.
