Thermal conductivity variations with temperature for solid phases in the Urea (U)-[X] mol pct 4-bromo-2-nitroaniline (BNA) system (X = 0, 2, 45, 89.9, 100) were measured using the radial heat flow method. From graphs of thermal conductivity variations with temperature, the thermal conductivities of the solid phases at their melting temperature and temperature coefficients for the U-[X] mol pct BNA system (X = 0, 2, 45, 89.9, 100) were found to be 0.26, 0.55, 0.46, 0.38, 0.23 W/Km and 0.007781, 0.005552, 0.002058, 0.002188, 0.002811 K -1 , respectively. The ratios of thermal conductivity of the liquid phase to thermal conductivity of the solid phase in the U-[X] mol pct BNA system (X = 0, 2, 45, 89.9, 100) were also measured to be 0.30, 0.44, 0.46, 0.49, 0.51, respectively, with a Bridgman-type directional solidification apparatus at their melting temperature. © 2013 The Minerals, Metals & Materials Society and ASM International.
