一般說明

氧化锗（VI），也称为锗或二氧化锗，是一种白色或灰白色粉末。它是一种高熔点（1600 °C）的难熔金属氧化物，具有优异的耐化学性。此外，氧化锗（VI）具有优异的光电性能，使其成为半导体工业中有价值的材料。它具有大约 2.1 的高折射率，比许多其他半导体材料的折射率高，并且具有低吸收系数。这些特性使其适用于波导、抗反射涂层和高折射率对比度涂层等应用。此外，锗（VI）具有约 3.1eV 的高带隙，并且在电磁光谱的红外区域中具有相对高的透明度，这使得它可用于红外探测器、LED 和太阳能电池等应用。

應用

无机纳米线的基材。[1]用于合成超高折射率和超低损耗的光波导。[2]

Questions

1–3 of 3 Questions  

  1. 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

  2. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Can you please check the particle size? I need it to answer the paper revision(until today...), help me please.

    1 answer

    1. The particle size of this material is not determined on a lot-by-lot basis. However, historical data indicates that this material is less than 74 um or -200 mesh.
