性狀
黑色粉末。相對(duì)密度6.88。熔點(diǎn)2042℃。不溶于水,能溶于酸生成相應(yīng)Ⅲ價(jià)鹽類(lèi)。導(dǎo)電性良好。
所屬類(lèi)別
無(wú)機(jī)化工產(chǎn)品: 無(wú)機(jī)鹽: Cq稀土元素化合物
用途與作用
是制鐠黃的原料,作陶瓷釉料色彩鮮艷。用于玻璃工業(yè)作著色劑,配成綠色,可仿制寶石。用作生產(chǎn)金屬鐠和制釤、鐠、鈷永磁合金的原料,及陶瓷器用黃色顏料。
合成工藝與制法
萃取法獨(dú)居石精礦經(jīng)堿溶、除磷、稀鹽酸浸出得氯化稀土溶液,用P2O4-煤油-HCl-ReCl體系萃取,可將稀土混合物分成輕、中、重稀土三組。萃余液La-Nd組輕稀土(含中稀土Sm2O3<1%),按草酸鹽沉淀次序?yàn)椋横?、釹、鐠、鈰、鑭,將其進(jìn)行分離??蓪⒉菟猁}沉淀生成可溶性絡(luò)合物后再沉淀使其分離,經(jīng)烘干,在1000℃灼燒得氧化鐠。其反應(yīng)式如下:
3Pr2(C2O4)3→Pr6O11+7CO2+11CO
