摘要: Cubic zinc oxide (rs-ZnO), metastable under normal conditions, was synthesized from the wurtzite modification (w-ZnO) at 7.7 GPa and ∼800 K in form of nanoparticles isolated NaCl matrix. The phase transition rs-ZnO → w-ZnO nanocrystalline ambient pressure experimentally studied for first time by using differential scanning calorimetry high-temperature X-ray diffraction analysis. It shown that occurs temperature range 370 to 430 its enthalpy 400 is −10.2 ± 0.5 kJ mol−1.
