Yttria-Stabilized Zirconia granules are granular ceramic materials made from zirconium oxide (ZrO₂) stabilized with yttrium oxide (Y₂O₃). YSZ granules offer excellent thermal stability, low thermal conductivity, and good resistance to thermal shock, making them widely used as feedstock for thermal spray coatings and advanced ceramic applications.
VIMATERIAL supplies YSZ granules with different yttria contents, including 3 mol% and 8 mol% Y₂O₃. Particle size, purity, and packaging can be customized according to specific coating and processing requirements. Contact us for more information.

Thermal Barrier Coatings
YSZ is one of the most widely used ceramic materials for thermal barrier coatings (TBCs). YSZ granules can be used as feedstock for thermal spray processes to form protective ceramic coatings on components exposed to high temperatures.
Plasma Spray Coatings
It is suitable for plasma spray coating processes, including atmospheric plasma spraying (APS) and other thermal spray technologies, depending on the particle size and feedstock specification.
Gas Turbine and Aerospace Components
YSZ coatings are widely investigated and used for thermal protection of gas turbine components, aircraft engine parts, combustion components, and other high-temperature systems.
Advanced Ceramic Coatings
It can also be used to prepare wear-resistant, thermal-resistant, and protective ceramic coatings for demanding industrial applications.
We can supply YSZ granules according to specific application and processing requirements, including:
For thermal spray applications, please provide your spraying technology, required particle size, Y₂O₃ content, and application so that we can recommend a suitable specification.
We apply strict quality control to raw materials and finished YSZ granules. Depending on the product specification, testing may include chemical composition, purity, particle size distribution, crystal phase, morphology, and other relevant properties.
Samples and technical data can be provided upon request.
It’s securely packaged to prevent moisture, contamination, and mechanical damage during storage and transportation.
Store in a clean, dry environment at room temperature and keep the container sealed when not in use. Customized packaging is available according to customer requirements.
It’s mainly used as ceramic feedstock for thermal spray coatings, thermal barrier coatings, plasma spray applications, and advanced ceramic coatings.
We offer different Y₂O₃ concentrations, including 3 mol% and 8 mol%, with customized compositions available upon request.
Particle size can be customized according to the thermal spray process, equipment, and coating requirements. Please contact us for available particle size specifications.
Yes. It can be supplied as feedstock for plasma spraying and other thermal spray processes, provided that the particle size and granule characteristics are matched to the specific equipment and process.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
