MICROSTRUCTURES OF POWDERS: A POSSIBILITY FOR IMPROVEMENT OF THE EFFECTIVE THERMAL CONDUCTIVITY FOR VACUUM-POWDER INSULATIONS.

Author(s) : PASTOR L.

Summary

THE RESULTS OF TESTS ON THE THERMAL CONDUCTIVITY OF EXPANDED PERLITE ARE GIVEN AND THEY ARE COMPARED WITH THE CONDUCTIVITY OF OTHER POWDER INSULANTS USED IN CRYOGENICS. THE MINIMUM DETERMINED THERMAL CONDUCTIVITY VALUE SUGGESTS THAT EXPANDED POWDER PERLITE CAN BE USED AT HELIUM TEMPERATURES.
