The Effect of Furan Resin Viscosity Molecular Weight on the Tensile Strength of Wettable Cathode with Carbon-bonded TiB2 Coating in Aluminum Electrolysis

Titanium diboride is one of the best aluminum wettable cathode materials for aluminum reduction cells. The carbon-bonded TiB 2 coating cathode can be used in current aluminum reduction cells. In this paper, the furan resin molecular weight and the tensile strength of wettable cathode with carbon-bonded TiB 2 coating were measured, and the relation between them was discussed. The results show that the increase in the viscosity molecular weight, ranging from 3?500 to 8?500, of the furan resin increased the tensile strength of wettable cathode with carbon-bonded TiB 2 coating. The results are meaningful for the application of carbon-bonded TiB 2 coating with a steady tensile strength in aluminum reduction cells.
