[0031]Lithium dispersion in oil, 55.72 grams, (11.275%) containing 6.28 grams of lithium with a medium particle size of 58 micron was charged into 120 ml hastelloy can equipped with a 1″ Teflon coated stir bar. The solution was heated to 75° C. and 0.63 grams of Luwax A (BASF) in a form of 10% solution in p-xylene (Aldrich) pre-dissolved at 72° C. was added to the lithium dispersion. This mixture was continuously stirred at 200 rpm for 22 hours. Sample was allowed to cool to the room temperature and transferred to the storage bottle. Further, lithium dispersion was filtered and washed three times with hexane in an enclosed, sintered glass filter funnel and twice with n-pentane to remove the hydrocarbon oil medium. The funnel was heated with a heat gun to remove traces of the solvents and the resulting free-flowing powder was transferred to a tightly capped storage bottles.

example 2
[0035]Lithium dispersion in oil, 780 g, (32.1%) that contained 250 g of lithium with a medium particle size of 63 micron was charged under constant flow of dry argon at room temperature to a 5 liter three neck glass flask reactor fitted with a stirring shaft connected to a fixed high speed stirrer motor. The reactor was equipped with bottom heating mantles. The reactor was then heated to about 75° C. and gentle stirring was maintained to ensure uniform distribution and heat transfer. 25 g of Luwax A (BASF) in a form of a 10% solution pre-dissolved in p-xylene at 72° C. was charged into the reactor and stirring continued for another 8 hours. The solution was then cooled slowly and kept at room temperature while being further stirred for 14 hrs and then transferred to the storage bottles. Further, lithium dispersion was filtered and washed three times with hexane in an enclosed, sintered glass filter funnel and twice with n-pentane to remove the hydrocarbon oil medium. The funnel was ...

[0037]Lithium dispersion in mineral oil 21.45 grams (27.5%) that contained 5.90 g of lithium and had medium particle size of 63 microns and 0.62 g Luwax A powder were charged under constant flow of dry argon at room temperature to a 125 ml glass flask reactor with a magnetic stirrer bar controlled by super magnetic stirrer. The reactor was equipped with bottom heating mantle. The reactor was then heated to the temperature range of 90° C. to 100° C. and stirring was maintained at ˜400 rpm to ensure uniform distribution and heat transfer for a period of about 1 hour followed by a natural cooling.
