一般描述

金红石型二氧化钛 (IV),也称二氧化钛,是一种颗粒尺寸小于100纳米的细小粉末。这种钛具有金红石晶体结构,也是一种具有高折射率的、不透明的白色结晶固体。它被广泛用作涂料、塑料、纸张和化妆品中的色素。金红石型二氧化钛纳米粉末具有高表面积,这使其在各种应用中反应活性更高、更有效。它耐热并且耐化学品,适用于高温和腐蚀性环境。

Questions

1–3 of 3 Questions  
  1. What is the Particle size distributions or atleast Mean particle size of these rutile nano particles. Whether this is hydrophobic or hydrophilic in nature?

    1 answer
    1. The mean particle size of this product is less than or equal to 100 nm, as listed in the properties section of the product page. However, no testing has been done to determine a distribution. Rutile Titanium(IV) oxide is generally considered hydrophilic due to its surface characteristics, which can interact favorably with water molecules.

  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.

  3. 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
