MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617099233 A) filed by Elysis Limited Partnership on August 17, 2026, for Electrolytic Cells Containing Fused Cast Refractories And Lining Components.
Inventors include Dynys, Joseph Michael; Deyoung, David Henry; Dastolfo Jr. , Leroy Edward; Dimilia, Robert Anthony; and Mackey, Allen George.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: It is disclosed an electrolytic cell for the production of aluminium by reaction of alumina, the electrolytic cell being configured to contain an electrolyte bath comprising alumina, the sidewalls of the cell being protected by fused cast refractory blocks comprising: from about 55 to 95 % of Al2O3 having alpha and beta alumina, wherein a beta alumina concentration is of about 40 to 60%, and about 5 to 45% of other oxides. The refractory blocks, object of the disclosed invention, are substantially free of cracks. Advantageously, the fused cast refractory blocks are impervious to the molten electrolyte bath and metals, are resistant to dissolution into said molten bath electrolyte and metals; and have a high electrical resistivity. A method for manufacturing the fused cast refractory blocks is also disclosed. The invention preferably concerns electrolytic cells working with inert or oxygen-evolving anodes for an Eco-friendly production of aluminum.
