Abstract：The inner wall and bottom of platinum-gold crucible treated by priming using 6.000 0 g of lithium tetraborate flux. Then, 0.600 0 g of sample, 1.500 0 g of sodium nitrate and 1.500 0 g of barium peroxide were mixed in the treated crucible. 50 mg of ammonium iodide was used as release agent. The sample was pre-oxidized at 750 ℃ for 35 min followed by melting at 1 100 ℃ for 15 min, avoiding the corrosion of platinum-gold crucible. The homogeneous glass beads were obtained. The calibration samples of silicon carbide-containing aluminum refractory material series were synthesized using the standard samples of aluminum refractory materials, silicon carbide and pure reagents. The contents of nine components (including aluminum oxide, total silicon, potassium oxide, iron oxide, manganese oxide, magnesium oxide, calcium oxide, titanium dioxide and phosphorus pentoxide) in silicon carbide-containing aluminum refractory materials were determined by X-ray fluorescence spectrometry (XRF). The precision test was conducted using the silicon carbide-containing aluminum refractory materials. It was found that the relative standard deviation (RSD, n=11) of major component aluminum oxide (w(Al2O3)=55.20%) and total silicon (w(TSi)=22.50%) was 0.20% and 0.23%, respectively. The RSD of other components was between 0.27% and 13.3%. The calibration sample of silicon carbide-containing aluminum refractory materials synthesized by the standard sample and pure reagents and the actual samples were analyzed by the proposed method. The found results were compared with the theoretical values and those obtained by the wet method, and the consistence was good.
