The concepts, experimental techniques, and theoretical
analyses of the surface energy of solid ceramic materials
are reviewed with the aim of condensing a large mass of
unrelated data into a concise form for comparison and
evaluation. It is shown that various experimental methods
can be applied to the measurement of surface energy, but,
that each of these has certain limitations which are
often unstated. Furthermore, it is shown that theoretical
analyses and empirical correlations, while sometimes
rather imprecise, can be used to approximate surface
energies, particularly as functions of temperature. While
a few materials have been discussed in considerable
detail (such as MgO, Al2O3 and some alkali halides), a
review of the literature notes that there is a great
paucity of information on the surface energies of many
solids of interest. Improvements and extensions of
experimental and empirical techniques are suggested that
will help to fill the voids in the present understanding
of ceramic solid surfaces, and specific analyses of
experimental methods are forwarded. It is shown in the
report that the proper use of thermodynamic techniques
offers considerable potential for the measurement and
interpretation of solid surface energies of a large
number of materials that are poorly understood at
present. In addition, the further development of
thermodynamic methods presents an opportunity to
investigate solid surface energies of nonbrittle
materials, thus overcoming one of the basic limitations
of the use of mechanical methods.
