Boron carbide is known to suffer from a loss in compressive strength in high pressure events due to amorphization. DFT simulations indicate that the introduction of silicon into the boron carbide lattice could mitigate this amorphization. Using rapid carbothermal reduction (RCR), within a temperature range of 1800-2000°C, the production of boron carbide powders lacking free carbon is possible. Using this method, incorporating silicon into the boron carbide lattice without the immediate production of silicon carbide becomes feasible. This incorporation is done via the addition of silicon from multiple sources, ranging from fumed silica to borosilicate xerogels, into the boron carbide precursor. The prepared powders are analyzed through x-ray diffraction, carbon analyses, and boron titration in order to determine their phases and stoichiometries, while bonding is analyzed via Raman spectroscopy. This will show that the incorporation of silicon possible and in agreement with the computational modeling, the addition will work to improve the performance of the boron carbide.
