A suite of thirteen Indian thermal coals have been subjected to FTIR examination to determine their quartz content. The coal samples were ashed at 815±10 °C using standard procedures and the high temperature ash (HTA) of each coal was used to make a tablet with KBr under pressure. Each tablet was then subjected to FTIR scanning to obtain a spectrum at a resolution of 2 cm−1. The 800 cm−1 quartz doublet observed in each spectrum was used to obtain quantitative information on the percentage of quartz present. The data were compared with interpretations from ash analysis. The result showed a good correlation between the two sets of data (R2=0.84), suggesting the potential of the method for routine testing of quartz content of coal in laboratory, especially as it takes less time than other methods.
