- ItemThe Structure around Iron lons and their Optical Absorption in Soda Lime Glass(Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 2004) Nagashima, Yukihito; Sakaguchi, Koichi; Uchino, TakashiIron oxide is the popular coloring component in the glass industry, but its importance is increasing incommercial flat glass because it is much more used than ever in the automotive application like ultraviolet ray and solar heat absorbing glass and low transmittance glass. But the structure around iron ions and their optical absorption are not fully understood yet and are still worth studying. The objective of this work is to examine the structure around iron ions in glass and to correlate it to their optical absorption. Iron exists in two states in glass, one is ferric ion and an other is ferrous ion. Ferric ion is usually thought to be in tetrahedral coordination and has absorption mainly in ultraviolet region and shorter wavelength region in the visible light. However it is reasonable to suppose the existence of octahedrally coordinated ferricion with stronger absorption in the same wavelength region, if glass contains larger amounts of iron oxide. Ferrous ion is in octahedral coordination and has absorption mainly in the infrared region and longer wavelength region in the visible light. The structure is very sensitive to the glass composition and to the thermal history after it is formed, and its optical absorption is relatively easily varied with them.

- ItemCovalent oxocomplexes and electrovalent coordination in glass(Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1989) Karlsson, Kaj H.The differenee in electronegativity between an oxide ion bonded to silicon and a metal ion gives a hint whether an oxoeomplex is expected or not. This has an implication for formulating correct stoichiometric reactions for transition metal ions in glass melts.
