[Narrow your material choices]() [Ask about your requirement]() ## Does the material need to store charge or conduct it? A shared oxide label does not make dielectric and conductive powders interchangeable. Narrow your material shortlist | Your requirement | Start by comparing | What can change the choice | Explore materials | | --- | --- | --- | --- | | Your component needs dielectric behavior | A titanate base chemistry or formulated MLCC powder | Specify the temperature target, electrode and firing process. The device, not loose powder alone, establishes capacitance performance. | [Barium titanate powder (BaTiO3)]()[Strontium titanate powder (SrTiO3)]()[Calcium zirconate powder (CaZrO3)]() | | Your formulation needs electrical conduction | ITO, ATO or AZO | Dopant level and specimen preparation matter. Check conductivity in the intended film or composite. | [Indium tin oxide powder (Sn-doped In2O3 / ITO)]()[Antimony tin oxide powder (Sb-doped SnO2 / ATO)]()[Aluminum-doped zinc oxide powder (Al-doped ZnO / AZO)]() | | Your task is optical emission or a phosphor | The specified host and dopant | A host powder and an activated phosphor are different requests; match the excitation and emission conditions. | [Yttrium aluminum garnet powder (Y3Al5O12)]()[Cerium-doped YAG phosphor powder ((Y(1-x)Cex)3Al5O12)]()[Calcium fluoride powder (CaF2)]() | Start with the task closest to yours. The examples identify material requests; a proposed grade still needs to fit your process and evaluation. ## MLCC and dielectric formulation Choose a base chemical when you formulate the dielectric yourself. Use the MLCC page for route-specific BTO and formulated X5R, X7R or C0G/NP0 target requests. ### Materials to explore [Barium titanate powder (BaTiO3)]() [Strontium titanate powder (SrTiO3)]() [Calcium zirconate powder (CaZrO3)]() [MLCC Dielectric Powders]() [Electronic & Functional Ceramics]() ### What changes the comparison Compare composition, particle structure, electrode system, firing atmosphere and evaluation conditions. [Discuss this task]() Diagram: MLCC cross-section: ceramic dielectric separates alternating electrodes connected to opposite end terminals Inside a multilayer ceramic capacitor ### Powder becomes the dielectric layer. **A Ceramic dielectric:** The fired ceramic separates adjacent internal electrodes. **B Internal electrodes:** Alternating layers connect to opposite ends. **C External terminals:** Two terminations connect the capacitor to the circuit. Schematic, not to scale. Chemistry, electrode system and firing conditions must work together. ## Doped conductive oxides ITO, ATO and AZO are different doped-oxide systems. Include the dopant level and whether the request is for loose powder or another supplied form. ### Materials to explore [Indium tin oxide powder (Sn-doped In2O3 / ITO)]() [Antimony tin oxide powder (Sb-doped SnO2 / ATO)]() [Aluminum-doped zinc oxide powder (Al-doped ZnO / AZO)]() [Electronic & Functional Ceramics]() ### What changes the comparison Compare composition and particle requirements alongside the specimen and method used for electrical data. [Discuss this task]() ## Semiconductor and silicide research Start with the complete compound or elemental identity. Application labels do not specify the impurity limits needed by the process. ### Materials to explore [Silicon powder (Si)]() [Molybdenum disulfide powder (MoS2)]() [Titanium disilicide powder (TiSi2)]() [Gallium oxide powder (Ga2O3)]() [Semiconductor & Chalcogenide Powders]() [Silicide Powders]() [High-Purity & Specialty Oxides]() ### What changes the comparison Keep phase, composition, critical impurities and deposition or preparation requirements explicit. [Discuss this task]() ## Optical and phosphor materials Separate the optical host from a doped phosphor and from an optical fluoride. ### Materials to explore [Yttrium aluminum garnet powder (Y3Al5O12)]() [Cerium-doped YAG phosphor powder ((Y(1-x)Cex)3Al5O12)]() [Calcium fluoride powder (CaF2)]() [Optical & Phosphor Materials]() ### What changes the comparison For phosphors, include dopant and excitation/emission conditions; for an optical powder process, specify form and impurity limits. [Discuss this task]() ## Prepare a useful comparison A reference datasheet or your existing material code is useful. If you are still exploring, describe what you are making and which result needs to change. - Compound, dopant/ratio and phase - Critical impurities and analytical basis - Particle profile and intended processing route - Device/material test conditions and documents [Prepare an application inquiry]()
