抄録

The low-temperature carbothermal nitridaton of boron oxide (B₂O₃) was induced by the networked carbon structure prepared from a condensed boric acid (H₃BO₃)-poly(vinyl alcohol) (PVA) product. The precursor powder consisting of B₂O₃ and carbon components was formed from the condensed product by thermal decomposition in air, and heated at 1200°C in a N₂ flow. The formation of boron nitride (BN) was accelerated for the product obtained from the precursor powder with the networked carbon structure. The formation of boron carbide (B₄C) by carbothermal reduction was also observed, and the formed B₄C was converted into BN with further increasing heat treatment time.
