Logarithmic Law

The carbon composite materials with silicon carbide coating were prepared for aluminum electrolysis as inert anode. The oxidation resistance, corrosion resistance and electrical conductivity are researched respectively. The results showed that the inert anode had high anti-oxidation, corrosion resistance and high conductivity. The oxidation kinetics curve of the material obeys typical line-logarithmic law. The corrosion occurs mainly before 25 hours. The electric conductivity was stable and good, had the electric conductivity property of the semiconductor. The conductivity increased with temperature increasing, the conductivity at 850°C was 102S/cm

Aluminum Electrolyte

A binary Cu–Ni alloy (69.93 wt. % Ni+Co) has been investigated as a potential inert anode in a laboratory electrolysis cell. When the electrolyte temperature, electrolyzing time and polar distance were set to be 960 °C, 4 h and 3 cm respectively, the corrosion resistance of Cu-Ni alloy materials in aluminum electrolyte was studied in the electrolyte composed of synthetic cryolite, alumina, aluminum fluoride, magnesium fluoride, calcium fluoride and aluminum by changing the molecular ratio of electrolyte, the concentration of alumina and current density of electrolyte, respectively. The results shows that the Cu-Ni alloy materials could reduce material loss when the electrolyte is with the optional conditions of the content of alumina in electrolyte approaching to 6 wt. %, the molecular ratio at about 2.2 and current density near to 0.5A/cm2. Thus the corrosion ratio of Cu-Ni alloy per year was measured to be 1.27cm/a.
