Electrical discharge in condensed matter at phase transitions

The discharge process in I-40A oil during its crystallization was investigated. The solidification of the liquid with the electrical discharge inside it did not lead to the termination of the discharge. At the same time, the breakdown of a single frozen drop does not occur even at voltages an order of magnitude higher than the breakdown voltage in a liquid. Spectroscopy of the electrical discharge in a single drop demonstrates its identity with the discharge in a bulk of liquid.
