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