✦ Synopsis

This paper includes the results of measurements of thermal conductivity k(T) of silver metallized microspheres at temperatures between 77 and 300 K The k(T) measurements have been performed in a calorimeter for three samples of different metallized concentration of microspheres ie O, 7 and 32%. The combined results prove the assumed diminishing of the radiation component of heat transport kr caused by metallization. The growth of the conduction component k c caused by metal at the sphere contact is observed simultaneously. The graphical dependence of the two components kc and kr on temperature is also presented.
