Didyoueverthink of using L I T H I U M as: A N Α Ν Τ Ι - F R E E Z E OR DE-ICING COMPOUND —
Lithium chloride solutions freeze as low as-67°E and are used for this reason in dry cells, fire extinguishers and as de-icers. ©
A CATALYST-
Synthetic rubber made from isoprene by using lithium as catalyst is remarkably similar to natural rubber in structure. The low cost of its use suggests it should be tried in other areas.
AN AIR CONDITIONER A N D REFRIGERANT—
Lithium chloride is extremely hygroscopic, highly soluble at low temperature, and has good thermal stability. In contact with air will maintain relative humidities from 10% up, over a wide temperature range. Such solutions may be used as heat transfer media to heat or cool and dry conditioned air. Lithium bromide is used as an absorbent in sealed industrial cooling units.
A ROCKET PROPELLANT—
Lithium hydride is a most convenient raw material for production of other "active" hydrogen-containing possible fuels, since it gives smooth reactions with high yields. In solid propellants, lithium c o m p o u n d s provide the highest percentage of active ingredients.
A CORROSION INHIBITOR—
Lithium dichromate offers good corrosion inhibition in cooling systems. Its solubility in organic fluids should extend the use fulness of many organics. @ Lithium metal (as low as 50 ppm) is used to remove gases from copper and increase electrical conductivity.
A DEGASIFIER— A FLUX—
Lithium fluoride, chloride, etc. with other salts produce com positions with low, favorable surface tension characteristics and excellent fluxing and deoxidizing properties, useful in produc tion and fabrication of such metals as aluminum, magnesium and titanium.
A N ELECTROLYTE ADDITIVE —
Lithium salts cause a pronounced increase in electrical conduc tivity, and lower melting temperatures when used in both aqueous and fused salt baths.
