European Supplier of High-Purity Tantalum Pentoxide, Niobium Oxide, and Strategic Rare Earth Oxides
EuStrategix is a European supplier of high-purity critical metal oxides and rare earth materials, specializing in tantalum pentoxide (Ta₂O₅), niobium oxide (Nb₂O₅), and selective high-purity rare earth oxides.
Based in Madrid, Spain, we provide REACH-compliant materials sourced from qualified producers and supplied with full documentation, traceability, and technical specifications.
Our focus is on supporting industries and research organizations that require high-purity materials, reliable sourcing, and responsive supply chains within Europe.
Reliable European Supply of Critical Metal Oxides
EuStrategix supplies high-purity tantalum oxide, niobium oxide powders and selected rare earths for advanced industrial and research applications across Europe. Our materials are used in industries that demand consistent purity, tight impurity control, and detailed analytical documentation.
Small-Lot and Pilot-Lot Rare Earth Oxides and High-Purity Materials
Unlike traditional bulk suppliers, EuStrategix focuses on small-lot and pilot-scale supply.
We support:
Research institutions
Pilot manufacturing programs
Materials validation
Specialized industrial applications
This approach allows customers to obtain small-lot and pilot-lot rare earth oxides in Europe without the large minimum orders often required by primary producers.
If a material is not currently in stock, we source it through our qualified supply network and ensure availability when needed.
Industries We Support
Our materials support a wide range of advanced industries:
Advanced ceramics and electroceramics
Optical coatings and photonics
Semiconductor and electronics manufacturing
Aerospace and high-temperature materials
Thin-film deposition and sputtering materials
Research institutions and R&D laboratories.
Quality Assurance and Documentation
All materials supplied by EuStrategix are accompanied by:
Manufacturer Certificate of Analysis (CoA)
Trace impurity analysis
Particle size distribution
REACH-compliant documentation
Supply chain traceability
These standards ensure our materials meet the expectations of European industrial, research, and regulatory environments.
We’re not Plan A.
We’re your backup supply line — the supplier Europe relies on when timing matters most.
A Responsive Partner for High-Purity Materials
