General description

Sodium metavanadate (SMV) is a vanadium salt that can be used as a corrosion inhibitor with good inhibition efficiency (98%) at 200 ppm. It can be used in the protection of carbon steel.[1][2]

Application


  • Study of electrical properties of cobalt oxide-doped sodium meta vanadate at different frequencies: This study explores the electrical properties of sodium metavanadate doped with cobalt oxide, emphasizing its significance in electrical insulation applications (Saleh & Deeb, 2022).

  • Chemical synthesis of vanadium oxide (V2O5) nanoparticles prepared by sodium metavanadate: This research demonstrates a simple chemical method to synthesize vanadium oxide nanoparticles using sodium metavanadate, highlighting potential uses in nanotechnology and material sciences (Farahmandjou & Abaeiyan, 2017).

  • Oxidative dehydrogenation of propane on silica-supported vanadyl sites promoted with sodium metavanadate: Discusses the catalytic properties of sodium metavanadate in the oxidative dehydrogenation of propane, underlining its potential in industrial chemical processes (Nadjafi et al., 2020).

In the present study, additive-free, pH-driven, hydrothermal crystallization was used to obtain shape-tailored monoclinic BiVO4 photocatalysts. The as-prepared BiVO4 products were systematically characterized, uncovering their crystallographic, morphologic and optical properties, while their applicability was verified in the visible light-driven photodegradation

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
