Lithium is the lightest known metal and can be alloyed with aluminium, copper, manganese, and cadmium to make strong, lightweight metals for aircraft. Lithium hydroxide (LiOH) is used to remove carbon dioxide from the atmosphere of spacecraft. Lithium stearate (LiC 18 H 35 O 2) is used as a general purpose and high temperature lubricant.
Lithium was initially found in the mineral petalite. It has also been found in the minerals spodumene and lepidolite. Lithium has the highest specific heat of any solid element, and is the lightest known metal. It can be readily alloyed with copper, manganese, aluminum, and cadmium to make strong alloys. Lithium is silvery-white in color.
Specific heat is the amount of heat required to raise one gram of a substance one degree Celsius. It can be thought of as a constant which gives the amount of heat that can be stored in a given mass by raising the temperature. For most gem species, the specific heat varies little from 0.2 callgrn OC.
Lithium. (Updated October 2017) Lithium is best known today as an ingredient of lithium-ion batteries. Li-7 as a hydroxide is important in controlling the chemistry of PWR cooling systems. Li-7 is a key component of fluoride coolant in molten salt reactors. Li-6 is a source of tritium for nuclear fusion, through low-energy nuclear fission.

some yellowish-brown spodumenes change color to purple on heating.
It shows that the -spodumene turns into -spodumene between 700 and 900 C before transitioning into -spodumene between 900 and 950 C . This would mean a decrease in the energy necessary to decrepitate the spodumene but does not consider the amount of energy needed to grind the material.
Jul 19, 2006 Lithium is most commonly extracted from spodumene. Naturally occurring - spodumene is converted - spodumene by heating to 1100C. - spodumene which is less dense is crushed and then mixed with sulphuric acid and heated to 250C, and extracting it into water producing a lithium sulphate (Li 2 SO 4 ) solution.
