METHOD OF PROTECTING CATHODE ASSEMBLY OF ALUMINIUM ELECTROLYSIS CELL

摘要

FIELD: chemistry. ^ SUBSTANCE: method involves deposition of a coating on coal-graphite blocks, where the said coating is molten silicon which is deposited through plasma sputtering at the bottom and sides of the coal-graphite blocks and has thickness of not more than 2 mm. ^ EFFECT: more efficient protection of the cathode assembly of an aluminium electrolysis cell.
