Dear all,
I would like to order LiAlH4 at Sigma-Aldrich, or any other official and completely legal shop, does anyone know a way how to do this as a private customer?

Periodically, ntom50 sells LAH on eBay. http://www.ebay.com/usr/ntom50
At the following link below you can see a recently closed listing.
http://www.ebay.com/itm/Lithiu…50g-97-min-/161561319162?
By sending ntom50 a message, you could determine when he will next sell some LiAlH4.
You can also "follow" ntom50 so you get alerts when he lists:

Another seller, dwsurman, also sells LAH:

See my earlier warning about ordering LiAlH4. I realize that chemically it may be the best way to go, but you will find it is probably easier to get or make other hydrides. You can always electrolyze water to generate modest amounts of hydrogen (it is the side of the cell producing twice the volume....) and do not let the two gases (H2 and O2) comingle! Handling hydrogen WAS under intense regulation as a consequence of the Hindenberg, but perhaps the subsequent interest in hydrogen as a fuel has lessened the fear a bit. Still, I understand working with hydrogen is particularly dangerous, like a few other reagents, it can literally be burning and you may not see the flame. I would caution anyone here to be very observant for all the reasons outlined here and elsewhere and perhaps for reasons about which I know nothing.
I attempted to purchase LAH from Sigma Alrdich, but was not able to do so as a private individual.
As best as I was able to determine, the criteria that they require in order to purchase it is that you need to be a corporation that is listed at a commercial address. Even then, it sounds like if you are not a recognized research institution or corporation with clear-cut 'legitimate' need of some sort, they are inclined to deny the sale rather than risk running afoul of the DEA.
There are a number of other suppliers of this common reagent, but I struck out with several of them, likely for the same reasons cited. They are afraid for their businesses, I suppose, and such a small sale is not worth the risk.
If you do have a corporation at a business address, then you will likely find a supplier, but as an individual it's quite difficult. For Sigma-Aldrich, the sale had to be made in the name of the business, they would not allow me to ship it to a commercial address under my name.
Have you tried Fisher Scientific? Check my bitly for search on proper CAS no, and list of hits. They have 25g powder bags as well, it seems.
It is Acros products, so one could perhaps also try directly the manufacturer,
They have 10g bags for 20 Euro .... 95% pure.
Note I have only googled it and have no personal experience of them or their products.
We have LiAlH4 for sale in small quantities at www.Lookingforheat.com. Also Nanoshell Lithium and (by month end) Lithium Hydride. We are also making Vacuum de-Oxidised and Hydrogen washed Nano-Nickel. All sent out packed in an Argon atmosphere.
I ordered some from Ebay, "Consolidated Chemical". It wasn't too expensive. Sigma-Aldrich wanted 100s of $ for shipping.
It seem they have a website: http://www.consolidated-chemical.com also.
I'm glad you found what you need at such a reasonable price, too. I note however they don't ship anywhere outside the continental USA.
It was before lookingforheat store was set up!
Still have to order the other correct powders. I do have some carbonyl process nickel-iron powder, but not pure nickel.
Though the topic is placed in one year ago, I still want to share this for future needs-Lithium aluminum hydride is available here at any quantity level, that's ensured by the company. As well as many other chemicals needed for researches like PIK-75. But I have no idea about if the company will sell such chemicals to individual or not. It can be consulted online.
Not all LiAlH4 is equal. The level of hydrogen content and contaminants can vary dramatically. Me356, for example, claims Alfa Aesar (owned by Johnson Matthey until a couple years ago) 97% LiAlH4 produced approximately twenty times as much hydrogen as what he had been using. I've read multiple examples of this on the internet: people used to very modest hydrogen release from LiAlH4. When they switch to another brand, they find the hydrogen output is increased.
When it comes to producing LENR, I think high purity is important. One method of producing high purity LiAlH4 is to purify it yourself chemically. Doing so is probably not an option for most replicators, however. The best brand of LiAlH4 to use from everything I have read is Alfa Aesar 97%. In some of the essays of different lots, the 97% purity turned out to be 99% pure. The 95% purity LiAlH4 linked to in a previous post could plausibly work, but I think it could possibly reduce the chance of producing excess heat.
The LiAlh4 decomposes slowly into Li3AlH6 : 3LiAlH4 -> Li3AlH6 + 2Al + 3H2 (Cfr T.N. Dymova, D.P. Aleksandrov, V.N. Konoplev, T.A. Silina, and
A.S. Sizareva, Russ. J. Coord. Chem. 20, 279 (1994.)
Half of the H2 content is gone with this first step of decomposition.
This decomposition starts at room temperature and the yield increases with the temperature. It is better to store the LiAlH4 in the fridge.
If Axil thinks Li6 is a PITA, try getting >1600 °C wire insulation across a border.
If you're looking for ceramic sleeving, try these folks:
http://css.coorstek.com/scripts/css512.wsc/op/op_indexB2C.html?inp_site=30&searchMode=drill
They have a large product line of various rigid ceramic sleeves including 3 grades of alumina that go to 1750C. These are available in double hole tubes for making thermocouple wells. I think they ship worldwide, but they do have a $150 minimum order.

For those interested, www.lookingforheat.com now has 100 grqms of Lithium Hydride in stock. Please email for further details.

Can a customer get Lithium 7 hydride? Lithium 6 is a poison/ash product of the LENR reaction.
The lithium we stock is over 90% Li7, as is all naturally occurring Lithium.
Songsheng and others have used ordinary LiAlH4 that is not isotopically pure and have produced great results.
My thinking is that what's most important when choosing your LiAlH4 is purity, particle size, and "freshness."
The higher purity you can go, the better. If someone has a professional lab and all the equipment required, LiAlH4 can be dissolved and purified into 100% pure (or 99.9%) LiAlH4. This substance will be snow white.
The particle size is also important. It allows for more effective desorption at a slightly lower temperature. Alfa Aesar seems to have a smaller particle size compared to other brands.
The use of new or fresh LiAlH4 is also important. It degrades naturally over time and after exposure -- even very brief -- to atmosphere or moisture of any kind.
The lithium we stock is over 90% Li7, as is all naturally occurring Lithium.
Tom Conover got a gainful rection going with Lithium 7 fluoride that he did not buy his material from LookingForHeat. Can you draw any lesson from this LENR success? Do you track what material works and what material does not work?
