英文摘要Amorphous Si2BC3N nanopowders (NPs) were heated at 1000-1700°C temperatures for 30 minutes in 1 atm N2. The changes in phases, chemical bonds, and microstructures were investigated by XRD, XPS, NMR, TEM, and first-principles calculation. Increases in heating temperatures lead to the nucleation and growth of SiC and BN(C) grains, along with partial transformation of SiC4units from amorphous to β/α-SiC, and collapse of B–C–N bonds. SiC nucleates prior to BN(C) at 1 atm, while it goes in the opposite order at high pressures (≥1 GPa). High pressures also shift the initial temperatures of crystallization of amorphous Si2BC3N NPs from 1400°C (1 atm) to 1150°C (5 GPa). © 2018 The American Ceramic Society
