Specify loose powder or prepared feedstock, together with the intended ceramic or coating process. #### Yttrium oxide powder Yttrium oxide powder (Y2O3) [Selection guide]() [Ask about this material]() Y2O3 #### Scandium oxide powder Scandium oxide powder (Sc2O3) [Selection guide]() [Ask about this material]() Sc2O3 ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Oxide identity** State the element and oxidation state or formula. A mixed rare-earth oxide is different from a specified single oxide. **Composition & purity** Distinguish total rare-earth oxide content, individual oxide content and trace impurities. Record the analytical basis. **Supply brief** Describe particle size, calcination or moisture requirements, quantity, use and destination. Review the current material documents with the proposed option. ## Before you choose **Are rare-earth metals and their oxides equivalent procurement items?** No. The chemistry, handling and processing tasks differ. An oxide specification cannot be used as the specification for an elemental rare-earth metal powder. **What does this directory cover?** This page covers oxide powders; elemental rare-earth metals have a separate directory. Shipment eligibility is reviewed for the exact material and destination. ## Rare-Earth Compound Powders Fluoride, oxyfluoride, hydroxide and Ce-Zr mixed-oxide powders for coating, ceramic and research requirements. Compare the chemical form and particle requirements. [Explore 9 sourcing directions]() ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Element, oxidation state and formula - Oxide content and purity reporting basis - Critical impurity and particle-size limits - Intended use, quantity and destination ### Quantity, samples and documents Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums. We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements. [How we coordinate documents]() [Samples and testing]() [Send a material request]() ## Applications to explore.
