Abstract Scope The market situation and environmental requirements suggest that the direct synthesis of Al-Si alloys in aluminium electrolysis cell can help to increase added value and reduce a total CO2 footprint of alloys. The aim of this paper was to determine the influence of SiO2 additives on the process control during the production of Al-Si alloy. The regulation of the process strongly depends on the electrical resistance of the electrolysis cells, so we determined the electrical conductivity of the electrolyte using the DC four-point method. The measured electrical conductivity was a guide for determining the dosing rate of SiO2. Optimization of the reduction process has been done with the process computer data and measuring the properties of the electrolyte with STARprobeTM. The promising results of direct Al-Si alloys synthesis in AP18 industrial cells could open a path to large variety of greener Al-alloys produced by electrolysis process.
