It is well known that the energy distribution, the spectrum profile of characteristic emission or absorption spectrum is affected by the electron orbit according to the binding state of atoms, and the analysis of those spectra became widely applied in order to investigate the binding state of constituent atoms.
The present study was performed in order to confirm how those spectra would be observed according to the co-ordination state of atoms in solid solution phases of the synthetic 3CaO·Al
2O
3-Na
2O system by means of electron microprobe spectroscopy.
The emission spectra energies were obtained from the mean value of 3/4 peak height position and analysis were carrired out on a standpoint of the spectra's half width and asymmetry index.
In this experiment, the CaLα and AlKα and their satellite line profile remained unchanged, even though Na
2O content was varied in 3CaO·Al
2O
3-Na
2O. Character changes for emission spectrum were observed in the OKα emission band spectrum structure of this system. That is the half width and asymmetry index of spectrum increase with Na
2O content and the ramification of spectrum profile is observed at the high energy side of the spectrum.
The reversion of ramified peak is not so easily determined, but it may be related to the existence of anisotropic oxygen atoms and this spectrum with any fine structure has never been observed through other oxide compounds.
