FIELD: metallurgy.
SUBSTANCE: starting particulate materials milled, sieved, is compacted, compressed and fired to ensure the strength of the consumable electrode. As starting material use a dry particulate mixture of non-metallic materials in the form of zirconium oxide 79-84 wt % of coal tar pitch and 16-21 wt %.
EFFECT: invention provides a consumable electrodes without using expensive metal charge materials.
