In consequence, aluminum can be found in steel as metallicaluminum and (so-called soluble aluminum), aluminum oxide and aluminumnitride. Metallic aluminum and aluminum nitride can be dissolved in acid and sothis part is called acid soluble aluminum or simply soluble aluminum.During thesteel production process, it is important to have a measure of the level of thesoluble aluminum in steel. Soluble and insoluble compounds in metals with spectrolab 167Fig. 7 â Evolution of the aluminum signal from the start of the analysis. Following this discovery, the peak integration method (PIM) was introducedat SIDEX in 2000.
