INERT ELECTRODE MATERIAL IN NANOCRYSTALLINE POWDER FORM

摘要

The invention relates to an inert electrode material in powder form comprising particles having an average particle size of 0.1 to 50 .mu.m and each formed of an agglomerate of grains of a ceramic material and grains of a met al or alloy with each grain of ceramic material comprising a nanocrystal of the ceramic material and each grain of metal or alloy comprising a nanocrystal of the metal or alloy. Alternatively, each particle can be formed of an agglomerate of grain s with each grain comprising a nanocrystal of a single phase ceramic material. The electrode material in powder form according to the invention is useful for t he manufacture of inert electrodes having improved thermal shock and corrosion resistance properties.
