Scandium is a rare earth metal with special properties used in advanced industries, particularly in the production of high-strength, lightweight aluminum alloys suitable for aerospace and automotive applications, as it enhances tensile strength and toughness of the alloys.

Additionally, scandium is used in special lamps, such as metal halide discharge lamps, which provide lighting close to natural light, making them ideal for stadiums, shopping malls, or film production.

In ceramic technology, scandium can improve the properties of ceramic materials to be more heat-resistant and stronger, thus used in engine parts or equipment operating in harsh conditions.

Scandium also plays a role in energy research, such as developing solid oxide fuel cells (SOFC), which require materials with good conductivity at high temperatures, and scandium can enhance the efficiency of electrolytes in these fuel cells.
