64. Characterization of coal ash by CCSEM technique

Abstract

Analysis of inorganic materials in three coals were carried out by CCSEM (Computer Controlled Scanning Electron Microscopy) technique. The method of sample preparation such as embedding of pulverized coal and polishing was examined. The conditions of measurement were also investigated. The minerals in the coal were determined from the composition of each ash particle obtained from ZAF correction. The comparison between the CCSEM and XRD analysis was conducted for the characterization of minerals in coal.
