SO3含量是评定水泥品质的一项重要指标。在GB/T176—2008《水泥化学分析方法》标准中给出了5种测定方法,其中作为基准法的BaSO4重量法,测定结果准确,但操作繁琐,耗时长。文献[1]采用高频炉燃烧—红外吸收光谱法,测定准确、快速。本文继续就该课题在多元助熔剂添加量、准确度和精密度的分析以及数据处理方法等方面进行讨论,确定了当样品的取样量约为0.1g,瓷坩埚中样品上下表面各添加0.5g多
SO3 content is an important indicator of cement quality assessment. In GB / T176-2008 “cement chemical analysis method” standard gives five kinds of determination methods, of which as a benchmark method BaSO4 weight method, the determination of the accuracy, but the operation is cumbersome and time-consuming. Literature [1] using high-frequency furnace combustion - infrared absorption spectrometry, determination of accurate and fast. In this paper, the subject of multi-flux flux amount, accuracy and precision of the analysis and data processing methods and other aspects discussed to determine when the sample sample volume of about 0.1g, the upper and lower porcelain crucible samples were added 0.5g many
