General description

Gallium is a rareearth element that is widely used in smart electronic devices and integratedcircuits as it provides the advantages of low energy consumption and highcomputational speeds. Due to its high boiling point and low melting point, itexhibits a wide temperature range in the liquid state. It tends to formsulfate, chloride, and phosphate complexes due to its high charge. Thecompounds of gallium find applications in advanced semiconductors and LEDchips.

Application

Gallium can be used as a precursor to synthesize:
  • Gallium nitride and other Ga-based compounds for optoelectronic applications.
  • Sulfur/gallium hybrid cathode material for lithium-sulfur batteries. The surface of Ga metal promotes the redox reaction of lithium polysulfides due to its electrocatalytic effect.
  • Ga-based liquid alloys for the fabrication offlexible electronic devices.

Features and Benefits

  • Excellent conductor of heat and electricity
  • Wide temperature range in the liquid state
  • Lowvapor pressure at high temperature

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
