Gadolinium Zirconium Suspension
Next-generation suspension feedstock for Suspension Plasma Spray (SPS) thermal barrier coating applications.
Introduction
Gadolinium Zirconate Suspension
Next-generation thermal spray materials
about
Developed for advanced SPS thermal barrier coatings
Gadolinium zirconate suspension is designed for the production of columnar thermal barrier coatings (TBCs) using Suspension Plasma Spray (SPS).
SPS offers an alternative route to Electron Beam Physical Vapour Deposition (EB-PVD), enabling columnar coating structures with low thermal conductivity and long service life.

Developed around your application
Advanced ceramic materials only deliver their full performance when engineered for the coating process. That is why Circle PGM focuses on application-driven material development rather than standard product specifications.
Our Gadolinium Zirconate suspension is developed for Suspension Plasma Spray (SPS) and can be adapted to meet specific process requirements, including solid content, solvent system and powder characteristics. From material selection to product qualification, we work closely with customers to support reliable coating performance and long-term process stability.

+31 (0) 85 018 9964How does Circle PGM handle logistics?
Circle PGM works with long term logistics partners across the globe. This ensures trustworthy and secure shipments
What materials can Circle PGM recover?
We handle a wide variety of materials containing precious metals (PGMs) in all shapes and sizes. Our specialty lies in iridium and ruthenium coated materials, which we process using our unique, chemical-free method.
Is Circle PGM compliant with European environmental regulations?
Yes, Circle PGM is compliant with European environmental regulations. Our innovative, chemical-free recovery process aligns with the standards for sustainability, safety, and environmental protection. We continue to improve on a daily basis.
What materials can be recovered and refined?
If your material contains precious metals, recovery is possible, even from very low concentrations. Whether it involves coated materials, solids, liquids, hazardous substances, organics, catalysts, or any other form shape or size, our team is here to assist you. Feel free to get in touch with us!
What’s the difference between destructive and non-destructive coating removal?
Destructive coating removal breaks down both the coating and the substrate, making the substrate unusable. Non-destructive removal, however, separates the coating while preserving the substrate, allowing it to be reused. At Circle PGM, we specialize in non-destructive, chemical-free method to recover precious metals sustainably
Let’s develop the right suspension together.
Every coating process is different. We work with customers to define suspension characteristics that align with their application, coating route and qualification requirements. From initial material selection to product qualification, our goal is to support reliable coating performance and long-term success.
