To determine the composition of metals and its physicochemical characteristics, the method of spectral analysis is used. This method is based on the study of individual radiation spectra in different atoms and molecules of matter. In metallurgy, the spectral analysis of metals is classified by types of spectra and the set tasks. The molecular spectral analysis is distinguished, the object of the study of which is molecules. In this case, the technique implies the study of absorption spectra during dispersion of light through the molecules. In this method, the molecular composition of the metal is determined. In addition, there is an atomic spectral analysis that studies the properties of atoms. With this study, the study is based on the analysis of ionic spectra of radiation and absorption. There is also an emissional research method for spectrum. This method is based on the study of the radiation spectra of molecules and atoms, which pass from a neutral state to excited by a powerful electromagnetic field. Another method of spectral analysis is called absorption. In this method, individual absorption spectra of various atoms and metals molecules are studied. Any spectral analysis is based on the unique properties of the electromagnetic nature of each individual chemical element. All metals radiate or absorb the quanta of electromagnetic radiation in accordance with their chemical composition. Today, the spectral analysis of metals is the most effective method of studying the composition of the substance. This method is used in industry for hard metal quality control.
