How to search Lithium aluminium hydride?

Lithium aluminium hydride, commonly abbreviated to LAH or known as LithAl, is an inorganic compound with the chemical formula LiAlH4. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Some related derivatives have been discussed for the hydrogen storage.
Applications: Use in organic chemistry, Inorganic chemistry, Hydrogen storage and other tetrahydridoaluminiumates

Are you buying Lithium-Aluminum Alloy?

Al-Li alloys are a series of alloys of aluminium and lithium, often also including copper and zirconium.
Al-Li alloys are primarily of interest to the aerospace industry due to the weight advantage they provide. They are currently used in a few commercial jetliner airframes, and the AgustaWestland EH101 helicopter.
The third and final version of the U.S. Space Shuttle's external tank was principally made of Al-Li. In addition, Al-Li alloys are also used on both the Atlas V and Delta IV EELV rockets, and before its cancellation were to be used by NASA for Project Constellation, primarily, on its Ares I and Ares V rockets, as well as the Orion spacecraft.

Lithium bromide

Lithium bromide, or LiBr, is a chemical compound of lithium and bromine. Its extreme hygroscopic character makes LiBr useful as a desiccant in certain air conditioning systems.
properties
Lithium bromide is prepared by treatment of lithium carbonate with hydrobromic acid. The salt forms several crystalline hydrates, unlike the other alkali metal bromides.
Uses
Lithium bromide is used in air-conditioning systems as desiccant. Otherwise the salt is useful as a reagent in organic synthesis.
Medical applications
Lithium bromide was used as a sedative. Like lithium carbonate and lithium chloride it was used as treatment for bipolar disorder.

What is Lithium sulfate?

Lithium sulfate is a white inorganic salt with the formula Li2SO4. It is the lithium salt of sulfuric acid.
Lithium sulfate is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature, as its dissolution is an endothermic process. This property is shared with few inorganic compounds, such as the lanthanoid sulfates.
Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However, they do suffer in this application because of their water solubility.

What is Lithium amide?

Lithium amide is an inorganic compound with the chemical formula Li+NH2-, i.e. it is composed of a lithium cation, and the conjugate base of ammonia. It is a white solid with a tetragonal crystal structure.
lithium amide may refer to lithium salts of amines e.g. Li+NR2-. An example of a lithium amide is lithium diisopropylamide (LDA), which is quite commonly used.
Lithium amide can be made by adding lithium metal to liquid ammonia
Lithium amides are very reactive compounds and can act as strong bases. Unless the nitrogen atom is hindered, as in the case of LDA, they can also act as nucleophiles.
