MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202531042706 A) filed by Indiano Refractories Private Limited on May 02, 2025, for Process For Producing Black Fused Alumina, Fused Azs, And Microfine Alumina Derived Materials From Aluminium Dross Residue Using An Electric Arc Furnace.
Inventor includes Rajeev Biyani.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The invention discloses a carbon-free process for producing black fused alumina and fused AZS materials using aluminium dross residue and mill scale as primary feedstock in an electric arc furnace. Metallic aluminium and aluminium nitride present in dross act as in-situ reducing agents converting iron oxides into FeO which reacts with alumina forming spinel phase. The process eliminates need for carbon reductants, reduces CO2 emissions, enables recovery of metallic iron byproduct and converts hazardous industrial waste into high value refractory material. The invention provides environmentally sustainable pathway for fused ceramic production compatible with existing electric arc furnace infrastructure.
