Abstract (en)
[origin: WO02075023A2] The invention relates to an inert electrode materil in powder form comprising particles having an avrage particle size of 0.1 to 100 um and each forme of an agglomerate of grains of a ceramic materialand grains of a metal or alloy with each grain of eramic material comprising a nanocrystal of the ceamic material and each grain of metal or alloy comrising a nanocrystal of the metal or alloy. Alterntively, each particle can be formed of an agglomerte of grains with each grain comprising a nanocrysal of a single phase ceeramic material, a metal oran alloy. The electrode material in powder form acording to the invention is useful for the manufactre of inert electrodes having improved thermal shok and corrosion resistance properties.

Alternatively, each particle can be formed of an agglomerate of grains with each grain comprising a nanocrystal of a single phase ceramic material, a metal or an alloy. The electrode material in powder form according to the invention is useful for the manufacture of inert electrodes having improved thermal shock and corrosion resistance properties.
