  • Boron - Wikipedia

    Boron carbide is a ceramic material which is obtained by decomposing B 2 O 3 with carbon in an electric furnace: 2 B 2 O 3 + 7 C → B 4 C + 6 CO Boron carbide's structure is only approximately B 4 C, and it shows a clear depletion of carbon from this suggested stoichiometric ratio.
