Deskripsi
Scandium (Sc) applications in solid oxygen fuel cells, aeronautics and heat exchange systems are forecasted to increase significantly without a sufficient continuous Sc supply for Europe. ScaVanger is an EU project for upscaling Sc extraction and purification technologies from various TiO<sub>2</sub> pigment production residues. High purity Sc<sub>2</sub>O<sub>3</sub> and ScF<sub>3</sub> will be produced at competitive prices for the EU market. The ScaVanger process is expected to result in a 10% higher production rate and higher product purity as processing starts with a unique cleaning process of actinides. The first plant at a major European TiO<sub>2</sub> pigment production site will be supplying about 30 t/a of Sc<sub>2</sub>O<sub>3</sub>.
