摘 要: | 文章用水热法合成了含氯方钠石粉末,并讨论了 NaCI的掺杂浓度、晶化时间和晶化温度对方钠石结构的影响。通过X射线衍射(XRD),扫描电镜(SEM)和热重分析(TG -DTA -DSC)对合成方钠石结构、形貌和热稳定性进行分析。结果表明,NaCI的掺杂量在2%~10%内合成样品产物为单一方钠石结构,当掺杂量达到20%时,合成产物结构发生变化,最佳晶化温度为80℃,晶化时间为6h。扫描电镜图片显示样品颗粒均匀,粒径为01.~02.μm。热重分析表明样品在230℃附近有吸热反应。

Abstract: | Sodalite single crystal were synthesized by hydrothermal method and the structure ,mor-phology ,thermal stability were analyzed by X ray diffraction ,scanning electron microscopy and thermo-gravimetric analyzer .Discussed the doping concentration of NaCl ,crystallization time ,crystallization tem-perature influence on the sodalite crystallization and the optimization of synthetic conditions .Results showed that ,the amount of NaCl doping in 2% -10% samples synthesized product was a single sodalite structure ,w hen the concentration reached 20% ,the change in the structure of synthetic product ,the opti-mal crystallization temperature is 80℃ ,reaction time is 6h .The synthetic product uniform particles diame-ter of 0 5.μm and has the endothermic reaction at 280 ℃ . |
