gadolinite

In 1843 , a Swedish chemist named Carl Gustaf Mosander took gadolinite and separated it into the rare-Earth materials yttria , erbia , and terbia .

1843年，瑞士化学家C.G.莫桑德尔把硅铍钇矿分解为稀土材料氧化钇、氧化铒和氧化铽。

Of or relating to diatoms of the class Pennales , distinguished by bilaterally symmetrical form . a soft silvery metallic element ; a rare earth of the lanthanide series ; it occurs in gadolinite and monazite and xenotime .

硅藻的属于或有关以双侧对称形状著名的硅藻的一种软质的银色稀土属金属元素，见于硅铍钇矿、独居石和磷钇矿中。

Mossbauer spectra of natural gadolinite and aeschynite were measured at 297K and 81K , respectively .

测定了天然硅铍钇矿和易解石在297K和81K时的~（57）Fe穆斯堡尔谱。

The Mossbauer spectrum of gadolinite consists of one Fe3 + doublet and two Fe2 + doublets , and the multiple Fe2 + doublets were attributed to the next nearest neighbour effect .

结果表明，硅铍钇矿的~（57）Fe穆斯堡尔谱是由一对Fe~（3+）双线和两对Fe~（2+）双线构成，其中的多重Fe~（2+）双线来源于次近邻效应。
