Abstract :
In this paper we examine the formation of bubbles in a point to plane geometry in different liquids: a synthetic insulating oil-monobenzyltoluene (BT) and a liquefied atomic gas (argon), under a continuous negative voltage. It has already been shown that in highly purified aliphatic hydrocarbons (e.g. cyclohexane) a bubble is systematically produced following a current pulse, and that these pulses occur at a frequency of the order of kHz under similar conditions to those here. We compare phenomena in the three liquids and explain the observed differences and similarities
