Abstract：0.2 g of sample was transferred into crucible containing(0.300± 0.005)g of tin particles. Then, (0.400±0.005)g pure iron and (2.000± 0.005)g tungsten particles were added for analysis. The determination method of carbon in ferrosilicon nitride by high frequency combustion infrared absorption was established. Since there were only few standard samples of ferrosilicon nitride in experiments, the calibration curves were prepared using standard sample (GSB 03-2469-2008,w(C)=0.35%) and synthetic sample (w(C)=0.025 7%, which was prepared using standard samples including 0.04 g of silicon nitride JCRMR 008 and 0.16 g of pure iron GBW 01148a). The linear range of carbon in proposed method was 0.025%-0.35%, and the detection limit was 0.000 45%. The synthetic sample 1 was prepared using 0.10 g of silicon nitride JCRM R008 and 0.10 g of pure iron GBW 01148a. The synthetic sample 2 was prepared using 0.08 g of ferrosilicon nitride GSB 03-2469-2008 and 0.12 g of silicon nitride JCRM R006. The content of carbon in synthetic samples was determined according to the experimental method. The found results were basically consistent with the certified values. The proposed method was applied to the determination of carbon in actual sample of ferrosilicon nitride. The relative standard deviations (RSD, n=6) were in the range of 1.2%-1.7%.
