Synthesis and thermogravimetric analysis of monoclinic yttrium citrate dihydrate

Abstract

AbstractThe 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.
