Abstract:

The samples were made into a glass melting piece at 1 050 ℃ with [m（Li₂B₄O₇）∶m（LiBO₂）∶m（LiF）=4.5∶1∶0.4] as flux at a dilution of 1∶30.The elements includingFe、Si、Al、Mg、Ca、Na、K、P in the melting piece were simultaneously determined by X-ray spectrometry.The calibration curve was carried out with the standard samples. Whose determination results obtained by X-ray fluorescence were calibrated with a theoretical a-coefficient.Results obtained by the method were in good accordance with those values determined by chemical methods.Relative standard deviation（n=10）for each component were in the range of 0.43%～5.86%.
