| 英文摘要 | A novel method was proposed for preparing oxychloride octahydrate by the two - step decomposition of zircon sand concentrate in sodium hydroxide system. The effect of decomposition temperature and NaOH - to - zircon mass ratio of each stage on the decomposition of zircon sand was investigated. The macrokinetics of the two - step decomposition process was also examined. The experimental date showed that the shrinking core model with diffusion through the residual layer is most applicable for the first step decomposition process with the apparent activation energy of 42.9 kJ/mol, but the second step process was controlled by chemical reaction with the apparent activation energy of 30.1 kJ/mol. 漏 (2014) Trans Tech Publications, Switzerland. |
