Lithium - Minerals Provide Unique Industrial Raw Material

MILITARY necessities and economic scarcities, occasioned by the first and second World Wars, led to the search for substitute materials and new products to meet the demands of advancing technology accelerated by research development. Among others, lithium came to attention. Its chemistry had been studied for a long period, but its general use was quite restricted due to limited known sources of raw material. In World War I, Germany used lithium metallurgically for two principal purposes: 1-hardened lead alloy, B-Metal, for railway bearings as a substitute for lead-tin-antimony alloys; and 2-light strong aluminum alloys, Scleron, in which zinc was largely substituted for copper.
