| Abstract: | Fourteen rare-earth (plus scandium and yttrium) orthophosphates have been synthesized and characterized for use as electron microprobe reference samples. These reference samples are single-element phosphates that are homogeneous, stable under the electron beam, and free of interfering elements. They have a stoichiometric composition (RPO4) with the element of interest (R) ranging from 32 to 64 weight percent. |
