Abstract

This study aims to elucidate the phase transformation of hexacelsian-to-celsian in 10 wt.% h-BN reinforced BaAl₂Si₂O₈ (BN/BAS) composites fabricated by hot-pressed at 1300 °C for different holding time. Results showed that the relationship between the transformation fraction of celsian and the holding time displays a typical “S” curve according to Johnson-Mehl-Avrami equation. During the hexacelsian-to-celsian transformation, a transitional phase of paracelsian was observed. Celsian tended to nucleate and grow up along the (110)_P habit plane of paracelsian by a non-diffusive transition behavior. During transformation, celsian and paracelsian present an oriented intergrowth with orientation relations of (110)_P//(020)_M, [001]_P//[101]_M and [11¯0]_P//[101¯]_M.
