Electrode material for electrolysis

Electrode material for electrolysis

Electrode material for electrolysis

(OP)
We are putting 30Kppm+ brine through an electrolysis cell and are losing the platinum off of the Pt plated Ti electrodes rapidly on the anolyte side. We experimented with a graphite electrode  and ran into some design problems with the porosity and erosion due to the tar/pitch that holds the particles in pressed/isomolded form. We want to start playing with some of the vacuum impregnated/corrosion enhanced graphites. I have heard of PTFE impregnated and another group that was using a phenolic impregnated graphite. Any suggestions?

RE: Electrode material for electrolysis

Brine composition?
Electrolysis temperature?
Current density?
Cell voltage?
Have you heard of Pourbaix diagrams?
Check ALL of those out.

RE: Electrode material for electrolysis

(OP)
Brine Composition: NaCl or KCl, corrosion has been the same

Electrolysis temp: Inlet brine temp is approx 15C

Current Density: Approx 0.1 Acm^-2

Cell Voltage: Approx 9V

I haven't heard of Pourbaix diagrams but am checking them out.
