Örnek Metin	We have computed the masses and decay constants of isotriplet π2(1670), the isoscalar η2(1645) and η2(1870) states as the ground-state nonet of 1 1D2 case within the Thermal QCD sum rules framework. This method is applied to the spectral changes of pseudotensor mesons at high temperatures including quark, gluon, and mixed condensates up to the five dimensions. We found that their masses and decay constants are insensitive to temperature in low-temperature region. At the near critical temperature, we observed an exponential decrease of the masses of π2(1670), η2(1645) and η2(1870), but while the decay constant of π2(1670) is fallen, that of η2(1645) and η2(1870) is increased as a function of temperature. The modification of condensates at T≠ 0 is crucial to the change of considered mesons properties in hot medium. We discuss and interpret the implications of the physical meaning of our results.
