Bubble formation from a centered single-hole nozzle placed on the bottom of a mercury bath has been investigated using an electroresistivity probe. The nozzle is made of brass and its surface is coated with fluororesin. Accordingly, the nozzle is poorly wetted by mercury. When the gas flow rate is lower than a certain critical value, the frequency of bubble formation is specified by the outer diameter of nozzle, <I>d<SUB>no</SUB></I>. On the other hand, when the gas flow rate is raised above another critical value, the inner diameter of nozzle, <I>d<SUB>ni</SUB></I>, governs the bubble formation. Empirical equations are proposed for the two critical gas flow rates. Bubble formation is affected by <I>d<SUB>no</SUB></I> and <I>d<SUB>ni</SUB></I> in the regime between the two critical gas flow rate values.
