草酸镨

草酸镨是镨的草酸盐，化学式为Pr2(C2O4)3，存在无水物和水合物。它的十水合物受热分解得到无水物，继续加热得到氧化镨。草酸镨在空气中加热分解，可以得到深棕色的十一氧化六镨。Sveda, Josef. The rare earths. [The oxidation of the oxalates of praseodymium and neodymium]. Casopis Ceskoslovenskeho Lekarnictva, 1927. 7. 226-232. CODEN: CCLEA3.它在氧气气氛中加热，能够检测到Pr(C2O4)2的生成。Pajakoff, Swetoslaw. Tetravalent compounds of praseodymium.  V.
