摘要：

The surface specification of Bredig palladium sols was investigated as a function of pH of the aqueous medium in which the palladium arcs were struck. A three-phase AC electric power supply rectified to 200 V DC was used. Positive and negative pole sockets were incorporated into the unit to allow switching of electrodes so that different metals could be arced. The results indicated that the sols arced at higher pH were more oxidised in nature.
