Abstract High pure wurtzite structure GaN has been synthesized by gas reaction method. Its structure was determined by powder x-ray diffraction using the Rietveld technique. The heat capacity C_p was measured from 113 to 1073 K , which can be represented by C_p = 0.362 + 3.010 x l0^-4T - 3.411 x 10³T^-2 - 7.791 x 10^-8T². No measurable phase transition was observed in this temperature range.
