[Browse 10 materials]() [Ask about supply]() [Image: Powder material specimens; appearance reference]() ## Choose a material ### Yttria-stabilized zirconia Identify the 3Y, 5Y or 8YSZ requirement and state whether the stabilizer content is expressed in mol% or wt%. Compare loose powder and granulated pressing feed separately. #### 3Y-TZP zirconia powder 3Y-TZP powder (3 mol% yttria-stabilized zirconia; verify grade convention) [Selection guide]() [Ask about this material]() ZrO2-Y2O3 system #### 5Y stabilized zirconia powder 5Y stabilized zirconia powder (yttria-stabilized zirconia; phase/grade-specific) [Selection guide]() [Ask about this material]() ZrO2-Y2O3 system #### 8YSZ zirconia powder 8YSZ powder (8 mol% yttria-stabilized zirconia; verify grade convention) [Selection guide]() [Ask about this material]() ZrO2-Y2O3 system ### Other stabilized zirconias Choose magnesia or calcia stabilization, then the composition and phase criteria. Use the intended forming and firing process to define particle requirements. #### Magnesia-stabilized zirconia powder magnesia-stabilized zirconia powder (MgO-ZrO2; Mg-PSZ only when grade confirms) [Selection guide]() [Ask about this material]() ZrO2-MgO system #### Calcia-stabilized zirconia powder calcia-stabilized zirconia powder (CaO-ZrO2; composition is grade-specific) [Selection guide]() [Ask about this material]() ZrO2-CaO system ### Composite and mixed-oxide ceramics ZTA, ATZ, spinel, mullite and cordierite are distinct systems. For composites, state which material is the main phase and how the composition is specified. #### Zirconia-toughened alumina powder zirconia-toughened alumina powder (ZTA) [Selection guide]() [Ask about this material]() Al2O3 + ZrO2 #### Alumina-toughened zirconia powder alumina-toughened zirconia powder (ATZ) [Selection guide]() [Ask about this material]() ZrO2 + Al2O3 #### Magnesium aluminate spinel powder magnesium aluminate spinel powder (MgAl2O4) [Selection guide]() [Ask about this material]() MgAl2O4 #### Mullite powder mullite ceramic powder (3Al2O3·2SiO2; nominal composition) [Selection guide]() [Ask about this material]() 3Al2O3·2SiO2 #### Cordierite powder cordierite ceramic powder (2MgO·2Al2O3·5SiO2) [Selection guide]() [Ask about this material]() 2MgO·2Al2O3·5SiO2 ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Composition & basis** Identify yttria, magnesia, calcia or the intended mixed-oxide system. State whether stabilizer content is reported in mol% or wt%. **Phase & feedstock form** Distinguish a loose fine powder, spray-dried granule and prepared feedstock. Define the phase or phase evidence required. **Processing window** Discuss particle distribution, binder/additives and the intended forming and firing route. Request data applicable to the candidate grade. ## Before you choose **Can two grades called YSZ be treated as interchangeable?** YSZ describes a family. Stabilizer content, phase, particle profile and additives can differ. Match the complete grade and processing brief before comparing options. **What does this directory cover?** ZTA, ATZ and other mixed oxides retain their own identities. Thermal-spray feedstock needs process-specific checks in the spray-powder directory. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Stabilizer chemistry and mol%/wt% basis - Target phase and additive/binder status - Loose powder or granulated feedstock - Particle profile and forming/firing route ### 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.
