摘要 采用高频燃烧红外吸收法，建立了测定碳化硼中总碳量的分析方法。对称样量、助熔剂进行了试验。结果表明，当称样量为0.02 g、助熔剂为0.2 g Fe+0.02 g B4C+0.2 g Fe+1.5 g W时，测定效果最佳。以CaCO3为校准物质，采用本法对碳化硼样品中的碳进行测定，结果与管式炉燃烧红外吸收法的相对偏差为0.09%，小于 JIS R2015-2007标准规定的允许误差0.20%，相对标准偏差为0.37%。
Abstract：A determination method of total carbon in boron carbide was established by high-frequency combustion infrared absorption method. Sample weight and flux used were discussed. It was found that the optimal experimental conditions were sample weight of 0.02 g and flux of 0.02g Fe +0.02 g B4C + 0.2g Fe +1.5 g W. The method was used for determination of carbon in boron carbide with CaCO3 as calibration materials. The relative error of the results with those obtained by tubular furnace combustion-infrared absorption method was 0.09 % which is smaller than the allowable error 0.20 %in JIS R2015. The relative standard deviation (RSD) was 0.37 %.
