  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Why should I use Product 323403, the LAH pellets, instead of a fine crystalline powder?

    The pellets are recommended for safety reasons. Powdered lithium aluminum hydride can form potentially explosive dust-air mixtures. But use of the lithium aluminum hydride pellets, which can tolerate exposure to air for a short period of time, avoids the dusting associated with the powder. Please note that longer dissolving times, perhaps up to 90 minutes at room temperature, need to be taken into account when using the pellet form.
