Electric Charge Generation by the Breaking of Frost Under a Temperature Gradient

[摘要] Measurement of the electric charge generated by the breaking of frost under a temperature gradient was performed in a cold room of -15°C. An electric charge of about 0.3 e.s.u./cm2 was generated by the breaking of frost under a temperature gradient of 10°C/cm. Negative electric charge was separated to warmer side of the frost. This electric charge is considered to be created at the breaking plane of frost under temperature gradient.
