Abstract

The method involves modifying a solid lining sample into fluid free from solid residue such as graphite/coke and silica. The fluid is analyzable by an inductively coupled plasma atomic emission spectroscopy (ICP-AES) to quantify chemical element contents of a complex composite material, through double weighing-out. The contents are quantified by processing one mixture obtained by adding 1 gram of metaborate of anhydrous lithium to crucible made of platinum/gold alloy, and another mixture by adding 3 drops of concentrated sulfuric acid and 5ml of hydrofluoric acid to crucible made of platinum.
