摘要：

Effect of TiO2 additives on nitridation of Si powders at 1300 degrees C and 1400 degrees C was studied by combining X-ray diffraction, thermogravimetric analysis, and thermodynamic calculations. Weak Si3N4 phase was detected in pure Si powders after nitridation at 1300 degrees C, whereas no Si3N4 phase was found in TiO(2-)doped Si powders and only secondary TiN phase was observed in addition to main Si phase. The TiO2 demonstrated an inhibiting effect on nitridation of Si powders at 1300 degrees C. However, the TiO2 led to the rapid nitridation of Si powders at 1400 degrees C by circulating reaction mechanism between TiO2 and TiN, and promoted alpha-to beta-Si3N4 phase transformation. In addition to TiN phase, secondary Si2N2O phase was observed in the TiO2-doped Si powders. The present study suggested that TiO2 additives exhibited effectively nitridation enhancing effect on the formation of reaction-bonded Si3N4 at 1400 degrees C. (C) 2016 Elsevier B.V.
