The instabilities in the electrical conductivity of barium sodium niobate (BSN) crystals are studied in the presence of ac and dc fields. Transitions from quasiperiodicity into chaos via phase locking are observed. Phase portraits, Poincaré sections and return maps constructed from measured voltage signals illustrate the emergence of a strange attractor from a torus. The dimension and entropy of the attractor are determined as a function of the control parameter.
