镍铁和镁铁水滑石的合成及热稳定性研究
Synthesis and Heat Stability of NiFe and MgFe Hydrotalcite-like Compounds
【摘要】 采用共沉淀法合成了摩尔比一致的镍铁和镁铁水滑石。X 射线晶体结构分析与TG DTA分析表明 ,镍铁与镁铁水滑石晶体两者结构相似 ,但热稳定性存在一定差异。
【Abstract】 NiFe and MgFe hydrotalcite-like compounds with identical molar ratio were synthesized by the method of coprecipitation. Their heat stability difference were compared by X-ray crystal structural analysis and TG-DTA analysis. The results showed a similar crystal structure and different heat stability.
