Thermal conductivity and dielectric behaviour are investigated on a SrTiO3 single crystal at low temperatures (0.1 K < T < 10 K and 0.05 K < T < 200 K respectively). The observed anomalies show that glassy behaviour is possible also at quantum paraelectric single crystal, which can be discussed in terms of lattice dynamics.
