    • Alternatively, the equilibrium constants were also calculated using the oxygen species listed in Table 3. In this case, it was assumed that oxygen atoms that are connected to 1 H atom and 1 or 2 Si atoms contribute to [OH melt, that oxygen atoms that are connected to 2 H atoms and 0 or 1 Si atom contribute to [H2Omelt, and that all other oxygen species (including isolated hydroxide fragments) do not contribute to either the peak at 4500 or 5200 cm-1 and hence are part of [O melt, Using this approach. In K, 1.3 ± 1.0 and 1.5 ± 0.5 for system 10W at 2000 and 3000 K, respectively. However, at higher temperatures, the In K values are more scattered and are generally lower than those found by searching for the two nearest-neighbor atoms of each oxygen atom
