Method of directly preparing aluminium cerium internediate alloy using fused salt elactrolysis method

Abstract

A proces for directly preparing the Al-Ce interalloy by fused salt electrolyzing method features that the pure cerium oxide is directly added to the electrolyzer and the chemical reaction in fused salt electrolyzing procedure makes the Ce directly come in Al liquid to obtain the RE alloy containing Ce (10%).

Description

1. Technical field: [0001] The invention belongs to the field of preparation methods of aluminum metal electrolysis, and in particular relates to a method for directly preparing aluminum-cerium master alloys by molten salt electrolysis. 2. Background technology: [0002] At present, the domestic production of aluminum-cerium master alloys mainly uses mixed rare earths to prepare low-content master alloys, and directly adds rare earth metals to the aluminum liquid to prepare alloy aluminum liquid. The composition of this method is not easy to control. It is not suitable to guarantee; there is also the direct preparation of mixed rare earth aluminum alloys by molten salt electrolysis, but the rare earth content can only be controlled at about 5%, and the production of this method will easily lead to changes in the technical conditions of the aluminum electrolytic cell, resulting in low efficiency of the electrolytic cell, and the rare earth Rare earth alloy products with high ...
