Antimony: A Small Metal with a Big Impact
Antimony is a critical raw material that plays an essential role in modern society. Although used in relatively small quantities, it is indispensable in technologies that support the energy transition, industrial manufacturing, safety applications, and strategic sectors.
Today, antimony has become increasingly important as governments and industries work to strengthen resilient supply chains and secure access to critical materials.
What is Antimony?
Antimony (Sb) is a naturally occurring element used in a wide range of industrial applications. Its unique chemical and physical properties make it difficult to replace in many products and manufacturing processes.
Key characteristics include:
- Flame-retardant properties
- High-performance alloys
- Chemical stability
- Semiconductor applications
- Catalyst and specialty chemical uses
Why is Antimony Critical?
Antimony is recognised as a Critical Raw Material by the European Union because it combines:
- High economic importance
- Significant supply risk
- Limited substitution possibilities
- Growing strategic demand
Reliable access to antimony is essential for Europe's industrial competitiveness and technological sovereignty.
Supporting Key Industries
Antimony contributes to numerous strategic sectors, including:
- Energy storage – lead-acid batteries remain essential for vehicles, telecommunications, backup power systems and renewable energy infrastructure.
- Fire safety – antimony compounds enhance the performance of flame-retardant systems used in buildings, transport and electronics.
- Automotive & Aerospace – specialised alloys improve durability and reliability.
- Industrial manufacturing – catalysts, glass production, pigments and plastics rely on antimony-based technologies.
- Defence and security – antimony is used in specialised applications supporting Europe's resilience.
Enabling the Green and Digital Transitions
The transition towards a low-carbon and digital economy depends on secure access to critical materials.
Antimony supports:
- Renewable energy systems
- Grid resilience
- Data centres and telecommunications
- Electrified transport
- Industrial innovation
As demand for advanced technologies grows, ensuring sustainable and responsible antimony supply becomes increasingly important.
Responsible and Sustainable Use
The antimony industry is committed to:
- Safe production and use
- High environmental standards
- Regulatory compliance
- Circular economy initiatives
- Responsible sourcing
- Innovation and continuous improvement
