Some Thermal and Electrical Properties of Candelilla Wax

Abstract

We report the values of some thermal and electrical properties of Candelilla Wax (euphorbia cerifera). The open-cell photoacoustic technique and another photothermic technique - based on the measure of the temperature decay of a heated sample - were employed to obtain the thermal diffusivity (${\alpha }_s=0.026\pm 0.00095{cm}^2/sec$) as well as the thermal conductivity ($k=2.132\pm 0.16W/mK$) of this wax. The Kelvin null method was used to measure the dark decay of the surface potential of the sample after a Corona Discharge, obtaining a resistivity of ${\rho }_e=5.98\pm 0.19\times 10^{17}ohm-cm$.
