The yttrium citrate was synthesized using freshly precipitated yttrium hydroxide and citric acid (or monosodium citrate) in the aqueous environment by the hydrothermal treatment at 80 °C or 100 °C. The properties of the samples were investigated using the CHN, XRD, TGA and static light scattering. Crystalline yttrium citrate dihydrate is formed by the reaction of citric acid with freshly precipitated yttrium hydroxide after 14 days of reaction at 80 or 100 °C. The thermogravimetric analysis of the crystalline sample of yttrium citrate dihydrate, thermal decomposition of the compound in the synthetic air occurs in four stages with the release of mainly water and carbon dioxide. Methane and propyne are formed in smaller amounts.

通过在80°C或100°C的水热处理，在水环境中使用新鲜沉淀的氢氧化钇和柠檬酸（或柠檬酸单钠）合成柠檬酸钇。使用CHN，XRD，TGA和静态光散射研究了样品的性能。在80或100°C下反应14天后，柠檬酸与新鲜沉淀的氢氧化钇反应生成柠檬酸钇二水合物结晶。柠檬酸钇二水合物晶体样品的热重分析，化合物在合成空气中的热分解发生四个阶段，主要释放出水和二氧化碳。甲烷和丙炔的生成量较小。
