See Chinese contents: YS/T 273.15-2012 YS/T 273.15-2012: Chemical analysis methods and physical properties of cryolite. Part 15: X-ray fluorescence spectrometric method for the determination of elements content using pressed powder tablets
This Part of YS/T 273 specifies the X-ray fluorescence spectrometric method for the determination of contents of fluorine, aluminum, sodium, silicon, iron, sulfur, phosphorus and calcium (respectively represented by F, Al, Na, SiO2, Fe2O3, SO42-, P2O5, CaO) and other elements in cryolite using pressed powder tables. This Part is applicable to the determination of fluorine, aluminum, sodium, silicon, iron, sulfur, phosphorus, calcium and other elements in cryolite. The measurement range is shown in Table 1.
