| 摘 要： | Si_2N_2O powder was synthesized by carbothermal reduction and nitridation natural quartz powder. At the same time, the effects of the process parameters such as SiO_2/C ratio, temperature and time on the compositions of products were analysed. It is found that the compositions of products depend closely on the parameters mentioned above, and that the product containing higher Si_2N_2O phase could be obtained by choosing suitable process parameters.

| Abstract: | Si2N2O powder was synthesized by car-bothermal reduction and nitridation natural quartz powder. At the same time, the effects of the process parameters such as SiO2/C ratio, temperature and time on the compositions of products were analysed. It is found that the compositions of products depend closely on the parameters mentioned above, and that the product containing higher Si2N2O phase could be obtained by choosing suitable process parameters. |
