Abstract: We use the non-perturbative Q\bar Q potential at finite temperatures derivedin the Field Correlator Method to obtain binding energies for the lowesteigenstates in the Q\bar Q and QQQ systems Q=c,b. The three-quark problem issolved by the hyperspherical method. The solution provides an estimate of themelting temperature and the radii for the different diquark and triquark boundstates. In particular we find that J-\psi and $ccc$ ground states survive up toT \sim 1.3 T c, where T c is the critical temperature, while the correspondingbottomonium states survive even up to higher temperature, T \sim 2.2 T c.
