Abstract

Small particles of Ti and Si were produced using a high-voltage discharge technique in aqueous solution. A Ti or Si electrode was cathodically polarized at a cell voltage higher than 180V in an electrolyte solution to trigger spark discharge between the electrode surface and the electrolyte solution. The spark discharge generated intense heat at the spark point and emitted melted materials into the solution. This process produced small particles of electrode materials in the solution. The particle size was in the range of ten nm to sub-μm for Ti and to 10μm for Si. XRD spectra indicated that the surfaces of the Ti particles were covered with oxide that had formed due to high-temperature oxidation in the aqueous solution. For the Si particles, XRD spectra showed only peaks attributed to Si crystals.<br>
