Thermal Conductivity of Powders [PDF]

Nature, 1949
ACCORDING to a note in Physical Abstracts1, R. L. Mullokandov2 finds that thermal conductivity of powders is practically due only to the convection in the surrounding gas, and that hence "a layer of smooth spherical particles in vacuum may be used as a good thermal insulator". This was discovered by M. Smoluchowski some forty years ago3.
