Correction: Boron-dependent microstructural evolution, thermal stability, and crystallization of mechanical alloying derived SiBCN

In this paper, the amorphous boron-rich SiBCN powders were prepared by high-energy ball-milling of the mixtures of inorganic Si, graphite, h-BN, and boron. The solid-state amorphization, thermal stability, and crystallization of the resulting SiBCN powders were studied in detail. Results showed that mechanical alloying can drive solid-state amorphization but also can be an initiation step for the nucleation of few SiC nanocrystals. The amorphous networks containing Si-C, C-B, C-C, C-N, BN, and C-B-N bonds are detected; however, solid-state NMR further confirms the formation of a new chemical environment around B atoms, BC3. The increases in boron content improve the thermal stability of SiBCN ceramics but weaken their oxidation resistance. Nano-SiC crystallizes first while BN(C) forms subsequently. Increasing boron content promoting SiC crystallization may result from the reduced hindering effects of B-N-C nanodomains that retard SiC crystallization.
