Spectroscopy of electric discharge plasma in metal vapours
The radial profiles of the temperature and electron density in the plasma of the electric arc between composition electrodes based on cooper (Cu-Mo, Cu-W) are studied by optical spectroscopy techniques. The electron density and the temperature in plasma as initial parameters were used in the calcula...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The radial profiles of the temperature and electron density in the plasma of the electric arc between composition electrodes based on cooper (Cu-Mo, Cu-W) are studied by optical spectroscopy techniques. The electron density and the temperature in plasma as initial parameters were used in the calculation of the plasma composition in local thermodynamical equilibrium (LTE) assumption. We used the Saha’s equation for copper, nitrogen, oxygen and W (or Mo) atoms, dissociation equation for nitrogen and oxygen atoms, the equation of plasma electrical neutrality and Dalton’s law as well. So, it would be possible to determine the amounts of metal vapours in plasma. |
