The experimental temperature-composition phase diagram of the binary system between hexadecane(C16H34) and 1-hexadecanol (C16H33OH) has been established by combining thermal analysis and powderX-ray diffraction (XRD). Beforehand, crystal structures of the solid ordered phases of the componentsinvolved were determined from XRD data. Hexadecane displays a triclinic form Tp belonging to thespace group P
, with Z = 1. The unit cell dimensions are a = 4.269 Å, b = 4.811 Å, c = 22.34 Å, 
= 84.54
, 
= 67.43, and 
= 73.00. 1-Hexadecanol displays a monoclinic form belonging to thespace group A2/a with Z = 8. The unit cell dimensions are a = 8.980 Å, b = 4.939 Å, c = 87.91 Å, and = 122.63. The phase diagram between both components is characterized by two invariants, a eutectic(located at T = 289.5 K) and a metatectic (located at T = 318.8 K). The miscibility in the solid state isvery restricted, limited to the regions rich in C16H34 and C16H33OH. Resulting alloys have led to thedesign of a double-wall glass for the thermal protection of liquid products between 13 and 18 C, effectivefor 4.5 h in an external environmental temperature of 24 C.
