Porous boron-carbide billets containing different amounts of carbon (0 – 15 wt%) were infiltrated with molten silicon to produce dense materials (ρ = 99.6% of theoretical) from starting B₄C powders with d_0.5 90 and 12.5 μm. The phase composition and microstructure of the material were studied. A solid solution of boron carbide in silicon was determined to be present.
