Dependency of thermal conductivity on the temperature and composition of d-camphor in the neopentylglycol–d-camphor alloys
چکیده انگلیسی

Dependencies of thermal conductivity of solid phases for neopentylglycol (NPG)–[x] wt.% d-camphor (DC), x = 0, 3, 30, 46, 70 and 96 alloys on temperature and composition have been investigated by using radial heat flow apparatus. From graphs of the solid phases thermal conductivity variations versus temperature, the thermal conductivities of the solid phases at their melting temperature and temperature coefficients for NPG–[x] wt.% DC, x = 0, 3, 30, 46, 70 and 96 alloys were found to be 0.29, 0.28, 0.27, 0.26, 0.25 and 0.24 W/Km and 0.002996, 0.002694, 0.005690, 0.010626, 0.003520 and 0.001404 K−1, respectively. The ratios of thermal conductivity of liquid phase to thermal conductivity of solid phase for NPG–[x] wt.% DC, x = 0, 3, 30, 46, 70 and 96 alloys at their melting temperature were found with a Bridgman type directional solidification apparatus to be 1.07, 0.93, 0.43, 0.50, 0.40 and 0.35, respectively.
