The rapidly growing development and progress in the semiconductor, solar panel, photovoltaic and also the catalytic industry, has recently considerably increased the production and the number of applications of high-purity metals. In order to ensure the extremely low level of impurities (ppm or even ppb range), complex and highly controlled processes are required.
The Pure Metals Group at IME focuses on alternative and cost-efficient methods, particularly based on the principle of fractional crystallization to produce high-purity metals such as Germanium, Indium, Antimony but also Aluminum, etc.
The group is equipped with three main ultra purification devices – zone melting , cooled finger and static crystallizer. 
Furthermore, the vacuum distillation is being investigated in this group too as a promising method for the synthesis of high-purity metals.
