This paper reports the synthesis of Nd₂(C₂O₄)₃.10H₂O with plate-like morphology employing the microwave-assisted precipitation as a new strategy. Thermogravimetric analysis (TGA-DTG) results supported the presence of 10 water molecules of hydration of the prepared neodymium oxalate, which decomposes to give neodymium oxide (Nd₂O₃) as a final product throughout the dioxy-carbonate intermediate formation. Based on its thermal behaviour, portions of the prepared neodymium oxalate were heated non-isothermally, utilizing a similar heating rate to that used in the TGA experiment, at the range 400–800 °C, then quenched to room temperature. Phase characterization indicated the formation of an amorphous carbonate phase at 400 °C, which crystallizes at 500 °C giving the hexagonal Nd₂O₂CO₃ phase. The formed Nd₂O₃ at the range 700–800 °C was found to have a high ability to absorb atmospheric water vapour forming Nd(OH)₃. The electrical conductivity measurements revealed strong dependence on the pre-treatment temperature, where the Nd-600 sample showed the highest values. The fluorescent properties of the pre-heated solids revealed the absence of a notable peak shift and fluorescence behaviour of the various samples was correlated with the structure modifications occurring during the pre-treatment.

本文报道了采用微波辅助沉淀法作为板状形态的Nd ₂（C ₂ O ₄）₃ .10H ₂ O的合成方法。热重分析（TGA-DTG）结果支持制备的草酸钕水合物的10个水分子水合，分解后生成氧化钕（Nd ₂ O ₃）作为最终产物贯穿碳酸二氧酯中间体的整个过程。根据其热行为，将部分制备的草酸钕钕进行非等温加热，并使用与TGA实验中相似的加热速率，在400-800°C的温度范围内，然后淬火至室温。相表征表明在400℃下形成无定形碳酸盐相，在500℃下结晶，得到六角形的Nd ₂ O ₂ CO ₃相。发现在700–800°C范围内形成的Nd ₂ O ₃具有吸收形成Nd（OH）_3的大气水蒸气的高能力。。电导率测量显示出强烈依赖于预处理温度，其中Nd-600样品显示出最高值。预热固体的荧光性质表明没有明显的峰移，并且各种样品的荧光行为与预处理期间发生的结构修饰相关。
