Development of a Clean Sealing Paste (HCF8O²) and High Performance Cathode Assembly with Improved Electrical Properties (HPCA)

Carbone Savoie has developed a new sealing paste in order to substitute coal tar pitch binder pitch and suppress all hazards linked to the PAH components. The electrical resisivity has been improved to insure a good electrical contact between collector bars and cathode blocks.
One recent development is the High Performance Cathode Assemblies (HPCA) produced in collaboration between Carbone Savoie and Metsol. The contact between cathode blocks and collector bars is done with sealing paste, together with electrically compensating plates and contact plugs to improve current distribution and enhance vertical current.

Elit, a new type of cathode for aluminium electrolysis

The document Development of a New Type of Cathode for Aluminium Electrolysis was presented at the 2016 ICSOBA Conference in Quebec. This is a new solution for aluminum plants seeking a block with intermediate properties between graphite cathodes and carbon cathodes....
