Abstract
A cell component for use in particular as anodes, cathodes and cell linings of cells for the electrolysis of alumina for the production of aluminum, comprising a solidified carbon containing paste consisting essentially of a compact mixture of one or more particulate carbonaceous material(s) with a non-carbonaceous binder and optionally with one or more fillers to form a fluid paste, the binder being a suspension of one or more colloids or being derived from one or more colloid precursors or colloid reagents optionally with chelating agents. A method of producing the cell component is also included.
Claims51
A cell component of an electrolytic cell for the production of aluminium by the electrolysis of alumina, such as an anode, a cathode or a cell lining, comprising a solidified carbon containing paste consisting substantially of a compact mixture of one or more particulate carbonaceous material(s) with a non-carbonaceous colloidal binder and optionally with one or more non-carbonaceous fillers, the binder being a suspension of one or more colloids, or being derived from one or more colloid precursors or colloid reagents optionally with one or more chelating agents.
A method of producing a cell component for use in particular as anodes, cathodes and cell linings of cells for the electrolysis of alumina for the production of aluminium, comprising the steps of:
- mixing one or more particulate carbonaceous material(s) with a non-carbonaceous binder and optionally with one or more fillers to form a fluid paste, the binder being a suspension of one or more colloids or being derived from one or more colloid precursors or colloid reagents optionally with chelating agents;
- and
- forming the paste to a desired shape and size, compacting and drying before use.
An electrolytic cell for the electrolysis of alumina for the production of aluminium comprising a cell component made of a carbon containing paste or a solidified carbon containing paste, which paste consists substantially of a compact mixture of one or more particulate carbonaceous material(s) with a non-carbonaceous colloidal binder and optionally with one or more fillers, the binder being a suspension of one or more colloids, or being derived from one or more colloid precursors or colloid reagents optionally with one or more chelating agents.
