The temperature dependence of the quadrupole interaction of <sup>181</sup>Ta in an antimony lattice has been studied using the time-dependent perturbed angular correlation method. The quadrupole interaction frequencies nu <sub>Q</sub> at 78, 293, 523 and 773K have been measured to be 499.5+or-1.3, 474.4+or-4.4, 454.9+or-3.8 and 425+or-4.8 MHz respectively. The effective EFG at 293K is (7.82+or-0.56)*10<sup>17</sup> V cm<sup>-2</sup> with the temperature coefficient alpha <sub>T</sub>=7.6*10<sup>-6</sup>K<sup>-3</sup>2/.
