Cathode Block
Cathode blocks are critical materials for production of primary aluminium. The blocks must withstand the combined effects of high temperatures and difficult electro chemical environment. Cathode blocks sare divided into 3 Types: carbon cathode blocks, semi-graphite cathode blocks and graphite cathode blocks.
