Anhydrous lithium tetraborate(Li2B4O7)and ammonium iodide were used as fluxes to melt and prepare samples at 1050℃.The primary and secondary elements in steel fluorite were determined by X-ray fluorescence spectroscopy.The miner-al effect in the sample during the determination process was eliminated by melting and matrix correction.The working curve was created using a series of standard samples,and the selection of experimental conditions,preparation of samples,and analy-sis results were described.The experiment shows that this method is simple,fast,precise,and has high accuracy in the results.
