The bulk magnetostriction of an YBa2Cu3O7 - x ceramic superconductor under the action of dc current pulses was measured at T = 77 K with the aid of a differential dilatometer with an error not exceeding 10-7. The magnetostriction in this material is negative and obeys a logarithmic law as function of the current density. It is demonstrated that a considerable contribution to magnetostriction of the YBa2Cu3O7 - x ceramics is due to the grain boundary layers.
