МАТЕРИАЛ ИНЕРТНОГО ЭЛЕКТРОДА В ВИДЕ НАНОКРИСТАЛЛИЧЕСКОГО ПОРОШКА

摘要

The invention relates to an inert electrode material in powder form comprising particles having an average particle size of 0.11 to 100 mum and each formed of an agglomerate of grains of a ceramic material and grains of a metal 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 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.
