Abstract: A titanium diboride wettable cathode includes a cold-pressed sintered block of titanium diboride, including a titanium diboride and an additive, the additive including a graphite, a carbon fiber and a titanium nitride; and a coating of titanium diboride, coated on a surface of the cold-pressed sintered block of titanium diboride.

Abstract: The disclosure provides a method for reducing perfluorocarbon emissions from an aluminum electrolysis, which belongs to the field of aluminum electrolysis. The method includes: placing an aluminum oxide in an electrolytic cell with set parameters for proceeding aluminum electrolysis, and regulating feeding parameters of the aluminum oxide to obtain an electrolyte; adding a set amount of LiF, KF, MgF2 and CaF2 into the electrolyte, and regulating a molar ratio of NaF and AlF3 in the electrolyte to reduce the perfluorocarbon emissions from the aluminum electrolysis.

Abstract: The present disclosure relates to a field of aluminum smelting, and in particular to an inert anode aluminum electrolytic cell with a vertical structure, which includes: an electrolytic cell shell (1), a heating device (5) and a graphite base (13). The electrolytic cell shell (1) is provided with three insulating layers therein. The heating device (5) is disposed in the groove on the first insulating layer (4) The graphite base (13) is disposed at a bottom of an inner cavity of the electrolytic cell shell (1). A bottom of the graphite base (13) is opened with a mounting slot. The cathode is vertically mounted in the installation slot. The anode (17) is arranged in a staggered manner with the cathodes (16) and is suspended above the electrolytic cell shell (1) by connecting to a guide rod (11).
