Type of article: Article

Summary

THE THERMAL CONDUCTIVITY OF A PARTICLE IS FIRSTLY ESTIMATED BY A SIMPLE CELL MODEL, THEN THE EFFECTIVE THERMAL CONDUCTIVITY OF THE POWDER IS CALCULATED ON THE ASSUMPTION THAT THE POWDER CONSISTS OF PARTICLES WITH THE ABOVE ESTIMATED THERMAL CONDUCTIVITY. THE EFFECTIVE THERMAL CONDUCTIVITIES OF THE POWDER OF PERLITE AND HOLLOW GLASS MICROSPHERE ARE MEASURED AT LOW TEMPERATURES, AND ARE COMPARED WITH THE CALCULATED VALUES. THE RESULT SHOWS THAT THE EXPERIMENTAL VALUES AGREE WELL WITH THE CALCULATED VALUES.
