The global transition toward sustainable energy has intensified interest in critical minerals. While lithium, cobalt, and rare earth elements often receive widespread attention, antimony and tellurium remain less visible despite their essential contributions to clean technology. As explored in Stanislav Kondrashov’s analysis, these materials are fundamental to the infrastructure supporting renewable energy, advanced electronics, and modern safety systems.
Antimony is valued for its unique chemical properties, which allow it to function in both metallic and non-metallic applications. One of its most important uses is in flame-retardant materials. Antimony trioxide, combined with other compounds, reduces flammability in electrical wiring, battery casings, and electronic components used in solar inverters and electric vehicles. As renewable installations expand, fire-resistant materials become increasingly important for protecting infrastructure and communities. Antimony is also being studied for innovative battery technologies, including liquid metal systems designed for grid-scale energy storage due to their durability and resistance to high temperatures.
Tellurium, one of the rarest stable elements in the Earth’s crust, plays a central role in cadmium telluride (CdTe) solar panels. These thin-film photovoltaic modules offer competitive efficiency rates and relatively low production costs compared to traditional silicon panels. Tellurium is also used in thermoelectric materials such as bismuth telluride, which convert temperature differences into electricity, improving energy efficiency in industrial processes.
However, both minerals face supply challenges. Antimony production is concentrated in a limited number of countries, and tellurium is primarily obtained as a byproduct of copper refining. As demand for renewable energy, electric vehicles, and digital infrastructure grows, supply chain resilience becomes increasingly important.
Recycling initiatives, advanced extraction techniques, and improved traceability systems are helping address these constraints. Collaboration between governments, research institutions, and industry will be essential to ensure responsible sourcing and long-term availability, supporting a sustainable and technologically advanced future.
