Boron Carbide B₂₅C and B₈C₁₈ Synthesized Using Boric Acid-Glucose and Boric Acid-Active Carbon at Low Temperature without Coreductor Materials

Abstract:

This study examines the formation of Boron carbide with a wide homogeneity range B₈C₁₈ and B₂₅C, from boric acid-glucose and boric acid-active carbon as precursor materials. The samples was analysed by means of X-ray diffraction and Fourier Transform Infrared spectrometer. X-ray diffraction pattern was analysed by GSAS software. X ray diffraction pattern of B₈C₁₈ shows peaks at 27^o, 39^o, 45^o, 65^o and 79^o, orthorhombic crystal system and lattice parameters a = 13.640 Ǻ, b = 7.8500 Ǻ and c = 12.910 Ǻ and space group P₂₁ ₂₁ ₂₁, whereas for B₂₅C sample show peaks at 2θ angle 28^o and 40^o, tetragonal crystal system, and the lattice parameters a = b = 8.753 Ǻ and c = 5.093 Ǻ and space group P-4 2 m. FTIR results show that for B₈C_{18 have}absorption bands with B-C bond at 1196.5 cm^-1, 0-H 3216.7 cm^-1 and B-O at 1477.1 cm^-1, whereas the formation B₂₅C have absorption bands with B-C bond at 1195.1 cm-1, O-H 3216.7 cm^-1 and B-O 1460.8 cm^-1.
