Process For Manufacturing Carbon Anodes For Aluminium Production Cells And Carbon Anodes Obtained From The Same
There is provided a process for manufacturing a carbonaceous anode for an electrolysis cell for the production of aluminium. The process comprises contacting coke particles with a boron-containing solution to obtain boron-impregnated coke particles, mixing the boron-impregnated coke particles with coal tar pitch to form an anode paste, and forming a green anode with the anode paste. A carbonaceous anode for an electrolysis cell for the production of aluminium is also provided, which comprises at least a first fraction of coke particle, a second fraction of coke particles and coal tar pitch, wherein at least the first faction of coke particles comprises boron-impregnated coke particles, the boron-impregnated coke particles being distributed throughout the carbonaceous anode. The carbonaceous anode presents good resistivity towards air and CO2 oxidation, which translates into less dusting of the anode, thus improving its integrity throughout its lifetime.
