Past approaches theorize amorphization in boron carbide to be mainly associated with chain bending, chain breakage which lead to potential disintegration of icosahedra due to different levels of stress. The reconciliation of Raman spectra for amorphized boron carbide has been a challenge because of the emergence of a broad band centered at 1340 cm-1, a relatively smaller band at 1810 cm-1 and a lesser predominant ‘hump’ at 1520 cm-1. These characteristics are absent in the crystalline spectrum and their origin has been a mystery till date. Past theories also suggest α-boron (α-B12), (B12)CCC and graphite to be formed during the amorphization process, however our recent DFT-based Raman spectral analyses suggests that spectral positions of these constituents are rather distant from the amorphization bands of boron carbide. We present a combination of DFT-evaluated spectral analysis and established thermodynamic arguments, and utilize these concepts in constructing a mechanistic elucidation of evolution of the unique spectral features in amorphization spectrum of boron carbide which have remained a mystery for more than a decade. The results help in resolving composition of the amorphous mix along with the mechanical constraints necessary to emanate the unique Raman spectrum of amorphized boron carbide.
