Use the complete stoichiometry and intended phase. [Browse 6 materials]() [Ask about supply]() [Image: Powder material specimens; appearance reference]() ## Choose a material ### Molybdenum and tungsten disilicides Specify the disilicide phase and composition. For a heating-material inquiry, include the forming process and operating environment used in evaluation. #### Molybdenum disilicide powder Molybdenum disilicide powder (MoSi2) [Selection guide]() [Ask about this material]() MoSi2 #### Tungsten disilicide powder Tungsten disilicide powder (WSi2) [Selection guide]() [Ask about this material]() WSi2 ### Titanium, tantalum and niobium disilicides Keep the metal-to-silicon ratio explicit. Compare phase and impurities against the intended electronic-material or ceramic research process. #### Titanium disilicide powder Titanium disilicide powder (TiSi2) [Selection guide]() [Ask about this material]() TiSi2 #### Tantalum disilicide powder Tantalum disilicide powder (TaSi2) [Selection guide]() [Ask about this material]() TaSi2 #### Niobium disilicide powder Niobium disilicide powder (NbSi2) [Selection guide]() [Ask about this material]() NbSi2 ### Magnesium silicide Use the Mg2Si identity and required phase evidence. Thermoelectric research requests also need the composition and evaluation conditions to be clear. #### Magnesium silicide powder Magnesium silicide powder (Mg2Si) [Selection guide]() [Ask about this material]() Mg2Si ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Silicide identity** Distinguish disilicides such as MoSi2 and WSi2 from Mg2Si and other stoichiometries. Include the target phase and allowable secondary phases. **Composition & particle profile** Describe silicon balance, oxygen and other critical impurities, together with the particle distribution and shape. **Processing context** Explain whether the powder is for compaction, a coating process, thermal or electronic research. This determines which data is useful. ## Before you choose **Is a silicide powder a blend of metal and silicon powders?** A compound powder and an elemental blend are different supplied materials. State whether you require a formed silicide phase and what phase-identification evidence is needed. **What does this directory cover?** Elemental silicon, metal powders and finished heating elements are outside this compound-powder directory. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Exact silicide formula and phase - Silicon balance and impurity limits - Particle distribution and morphology - Process, atmosphere and required evidence ### 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.
