In situ synthesis of B₄C/TiB₂ composites from low cost sugar based precursor

In the present study, a method based on sulfuric acid dehydration of sugar was developed to synthesis a precursor material, which can yield B ₄C/TiB₂ composites at much lower temperatures compared to traditional carbothermal methods. The precursor material for pure B₄C and B₄C/TiB₂ composites were heat treated at 1650°C under Ar and Ar+H₂ atmosphere. Then the samples were characterized by X-ray diffraction (XRD) and crystallized B₄C and B ₄C/TiB₂ composites can be obtained at 1650°C.
