    Niobium powder

    Niobium powder, a powder of metallic niobium, on the surface of which a dense oxide film is produced with unidirectional conductive valve-metal properties.

    Its oxide niobium oxide Nb2O5 is a white powder with a purity of up to 99.999% and is used in the production of high purity lithium niobate crystals and additives for special optical glasses.

    This anodic oxide film has stable chemical properties, high resistivity, low leakage current and a large dielectric constant. The electrical properties of niobium powder for capacitors have a specific capacitance of 3300 to 3600 μF-V/g and a leakage current value of 1 x 10-3 μA/(μF-V). Produced by reduction-hydrogenation method, sodium reduction method, etc.

    Niobium Powder Properties & Application

    • High resistivity
    • low leakage current
    • high dielectric constant
    • Used in the manufacture of electrolytic capacitors as well as walkie-talkie and general industrial electrical equipment.

    Characteristics of Niobium Powder

    • Low pick-up of oxygen and other impurities
    • Perfectly spherical and essentially satellite-free
    • Narrow particle size distribution.
    • high flowability and high packing density
    • Low internal porosity

    Most frequent questions and answers

    If you have questions or at any point or can’t find the answer you were looking for, call or email us directly at [email protected]. For issues about your orders or our refunds, please refer to our Team. Helping you answer all your questions and solving any problems you may have is our number one priority.

    We are the 100% manufacturer specialized in Additive Manufacturing.

    Sure. We accept custom orders and OEM/ODM.

    You can get a quote by visiting the Request a Quote page, requesting a quote on a product page, phone, email, or from our live chat. Based on a large variance of requirements from project to project, most quotations need to be prepared by a packaging estimator. RFQs can be emailed directly to [email protected].
    You will typically receive your quotation within 1-2 business days for most requests. RFQs and complex projects may require more time.

    High quantity orders generally net a lower cost-per-unit on all of our orders. For greater savings for your project, you can consult one of our Product Specialists for a customized strategy based on your business requirements and project goals.

    We make products easy for our customers. While the steps can differ from project to project, our typical process consists of the following stages:
    1.    Specification & Project Consultation
    2.    Quotation
    3.    Sampling and Prototyping
    4.    Production
    5.    Shipping and Fulfillment

    We offer a wide range of Additive Manufacturing such as SEBM, PREP and more than 40 different compositions of high-quality spherical metal powders, such as TiNi, TiTa, TiAl, TiNbZr and CoCrMo with fully customizable options.

    Most products need to be shipped by sea, but samples used only for testing may be shipped by courier and air to ensure timeliness. All of our products are carefully packaged with care to withstand the potentially harsh elements of travel. You can expect your products to arrive in the same condition they left our facilities.

    Production time can range from 5 to 25 business days depending on products type, requirements many other factors. Greater customization with more additional processes generally yields slightly longer production times. For your best estimate in the timeline, consult with your Product Specialist.

    While our products technically have no minimum order quantities, recommended MOQs are in place (which will differ based on products type, printing, or processes) to prevent individual unit prices from becoming too costly to recommend.

    The minimum order quantity we can usually provide is 1-20kg for samples(based on the detailed products) and 100-200kg for official orders. But it may vary by product, so, please check with your Product Specialist to learn the recommended MOQ of any of our products.
