PYROPHORIC MATERIAL. Any liquid or solid that will ignite spontaneously in air at about 130F (54.4C). Titanium dichloride and phosphorus are examples of pyrophoric solids tnbutylaluminum and related compounds are pyrophoric liquids. Sodium, butyLithium, and lithium hydride are spontaneously flammable in moist air because they react exothermically with water, Such materials must be stored in an atmosphere of inert gas or under kerosene. Some alloys (barium, misch metal) are called pyrophoric because they spark when slight friclion is applied. 

ARTIC (74-87-3) Flammable gas (flash point <32°F/<0 C). Moisture causes decomposition. Violent reaction with strong oxidizers, acetylene, anhydrous ammonia, amines, fluorine, interhalogens, magnesium, potassium, sodium, zinc, and their alloys. Reacts with barium, lithium, titanium. Contact with powdered aluminum or aluminum chloride forms pyrophoric trimethylaluminum may cau.se ignition or explosion. Attacks plastics, rubber, and coatings.

Forms heat- or shock-sensitive compounds with ammonia, silver azide, potassium, sodium, oxygen difluoride. Incompatible with aluminum-titanium alloy, barium acetylide, ethanol, formamide, halogens, mercmic oxide, mercurous chloride, oxygen, pyridine, pyrogallic acid, salicylic acid sodium hydride, sodium salicylate, sulfides, and other materials. 

At the heart of this device is a barium-lithium alloy, in a 1 to 4 atomic ratio [41], able to efficiently chemically absorb a large amount of nitrogen at room temperature, up to more than 2500 Pa-1 (N2)/g (alloy) [42].

Interesting support to the belief that the compound Pd2Pb can exist is afforded by the results of experiments 5 to determine the difference of potential between various alloys and pure lead in a normal solution of lead nitrate. The alloys were prepared by melting the palladium and lead under a mixture of lithium chloride and either potassium or barium chloride. Alloys containing less than 33 per cent, of palladium have a potential practically identical with that of pure lead, whilst those containing more than this amount of palladium exhibit a higher potential, which at first rapidly increases with the palladium. Between 20 and 90 per cent, of palladium the alloys are harder than the individual components, a maximum occurring with 65 per cent, of palladium. 

The preparation of the metal was first reported by von Grosse (80) who obtained it by bombarding protactinium pentoxide with 35 keV electrons in a high vacuum and by decomposing the pentachloride on a hot wire. No properties were reported for these products and more recently the pure metal has been obtained by reduction of protactinium tetrafluoride with lithium (73) or barium (65,125) vapor at 1300°-1400°C using the double crucible technique and on a larger scale by reduction with barium (106) or 10% magnesium in zinc alloy (107). 

The metals are employed in a variety of alloys. Lithium generally hardens and strengthens, but also causes embrittlement from 0.05 to 0.1% is used in Al, Zn and Mg alloys. Sodium is an important additive to lead such an alloy is the basis of the manufacture of lead tetraethyl, and another, containing 0.6% Na, 0.6% Ca and 0.05% Li, is a bearing metal. Ternary alloys of caesium with aluminium and either barium or strontium are used in photoelectric cells. Liquid sodium or sodium-potassium alloy is employed to transfer heat from the core of certain atomic reactors, e.g. Dounreay fast breeder.
