Fused Hydroxides as Acid-Base Analog Systems
G. P. Smith
Metallurgy Division
If fundamental research is to make an effective
contribution to the development of hydroxide
technology, one of the primary goals must be the
evolution of a systematic chemistry of these sub-
stances. No such systematic chemistry now exists,
It is the purpose of this research to establish a
theoretical basis on which such a systematic
chemistry can be built,
In the first report on this investigation' the
arious types of self-decomposition equilibria in
ides were considered with the aid of
cs. In the case of sodium hydroxide

these equilibria may be represented as follows:
Equilibria I and II are far to the left except qt very
high temperatures. Equilibrium Ill favors the oxide
over the peroxide, although somewhat less so at
higher temperatures than at lower temperatures,
This report is devoted almost exclusively to the
qualitative application of two acid-base analog
theories to Equilibrium I. This is, of Course, only
a small part of fused hydroxide chemistry, and the
conclusions reached will not, by themselves, tell
very much about corrosion phenomena. However,
they are an essential part of the over-all corrosion
picture.
