ANODE SPACE FILLER Russian patent published in 2016 - IPC C23F13/12 

FIELD: chemistry.

SUBSTANCE: invention relates to electrochemical cathodic protection of underground structures against corrosion and can be used as filler for anode space of anode beds in systems of electrochemical protection in oil, gas, power industry, as well as in municipal services. Filler contains a base and active components, wherein base includes ferrosilide wastes from production of anode beds and, as active components - synthetic sodium sulphate, calcium hydroxide and carboxymethyl cellulose in following proportions, wt%: synthetic sodium sulphate 5-20, calcium hydroxide 5-10, carboxymethyl cellulose 1-5 and ferrosilide wastes from production of anode beds - balance.

EFFECT: invention provides increased drainage capacity of filler, low transient resistance of earthing electrode-ground, decelerated anodic dissolution, reduction of current-spreading resistance from anode, ensuring continuity and homogeneity of filler.
