  A Hawking-Page phase transition between AdS thermal and AdS Black Hole was
presented as a mechanism for explaining the QCD deconfinement phase transition
within holographic models. In order to implement temperature dependence in the
confined phase we use a hard-wall AdS/QCD model, where the geometry at low
temperatures is described also by a Black Hole metric. We then investigate the
temperature dependence of glueball states described as gravitons propagating in
deformed background spaces. Finally, we use potential models to physically
describe the implications of our study.
