Coal-fired power plants still account for a large proportion in the total power generation while the “low-carbon society” is the apparent trend all over the world. When coal is burned in the boiler of power plant, the ash called “coal fly ash” is absolutely generated in it and mostly recycled in the cement industry. In using the fly ash as a raw material of cement, it is very important to analyze the components accurately to ensure the quality of the products.
X-ray fluorescence spectrometry is already used widely in the cement industry as the powerful tool for controlling the quality of both raw materials and products and provided as an analysis standard in many countries. XRF is suitable for requirement of routine analysis because of its simplicity of sample preparation, high precision and rapidity of analysis.
There are mainly two sample preparation methods in XRF analysis for the cement industry, one is a pressed powder method (briquette method) and the other is a fusion bead method. In selecting a sample preparation method, the inhomogeneity of the sample should be fully considered, because the inhomogeneity of the sample makes the analysis results worse. Since the sample is fused into a flux homogeneously, the powder sample of raw material such as coal fly ash is recommended to be prepared through the fusion bead method.
On the basis of Rigaku’s experiences and knowledges in WDXRF analysis technique developing for a long time, Rigaku has produced a new function “Automatic Quant Application Setup” and released for ZSX Primus IV and ZSX Primus IVi systems. This application note will demonstrate the “Automatic Quant Application Setup” function in the quantitative analysis for coal fly ash by fusion bead method.
