EVALUATION OF THE PROPORTIONALITY COEFFICIENT IN THE RUSANOV’S FORMULA FOR THE SURFACE TENSION USING KINETIC DATA ON RATES OF EVAPORATION OF NANOPARTICLES AND SHRINGKAGE OF VACANCY PORES

Abstract

Using experimental data on the evaporation rate of small metal particles (silver, lead) and of the rate of shrinkage of vacancy pores (aluminum), intervals of the reliability are estimated for the proportionality coefficient in Rusanov’s linear dependence σ=Kr between the surface tension σ and the particle radius r . The results obtained are compared to earlier estimations by E.N. Vitol (1992) and other authors.
