  The status of the literature is reviewed for thermophysical properties of
pure polycrystalline solid and liquid beryllium which constitute input for the
modelling of intense plasma-surface interaction phenomena that are important
for fusion applications (thermal analysis, vapor shielding, melt motion,
arcing, dust generation, dust transport). Reliable experimental data are
analyzed for the latent heats, specific isobaric heat capacity, electrical
resistivity, thermal conductivity, mass density, vapor pressure, work function,
total hemispherical emissivity and absolute thermoelectric power from the room
temperature up to the normal boiling point of beryllium as well as for the
surface tension and the dynamic viscosity across the liquid state. Analytical
expressions are recommended for the temperature dependence of these
thermophysical properties, which involve high temperature extrapolations given
the absence of extended liquid beryllium measurements.
