Impurity Oxygen-Triggered α- → β-Si3N4 Phase Transformation at 1900 °C

Autor: Hisayuki Imamura, Kazuhiro Kura, Tsunehiro Kawata, Sawao Honda, Toru Asaka, Yuji Iwamoto

Publikováno v: Crystals, Vol 13, Iss 11, p 1572 (2023)

Oxide additive-free α- → β-Si3N4 phase transformation of a high-purity commercial α-Si3N4 powder was investigated at 1600 to 1900 °C under a nitrogen pressure of 980 kPa. The XRD analysis revealed that the α- → β-Si3N4 phase transformation
