Spodumene - an overview ScienceDirect Topics

A temperature of 950 °C promotes the conversion of the metastable quartz to a β-spodumene solid solution, accompanied by an increase in grain size of about 1 μm. The completion of the heat treatment at 1125 °C in 0.5 h leads to only minor grain growth (Chyung 1969).

Phase Transitions in the α–γ–β Spodumene

Heat-treatment of spodumene concentrate at 1323 K (1050 °C) for 30 min in a rotary kiln yielded a successful decrepitation. Particle size decreased from 2 cm to less than 425 µm for 80% of the initial mass. X-ray analysis of both fractions did not reveal the presence of α-spodumene or γ-spodumene. The coarse fraction was ground to less than 425 micro;m with minimal mechanical energy and ...

2016-11-1  During the calcination, α-spodumene, which has a monoclinic crystal structure and specific gravity of 3.15 g/cm 3, is transformed into β-spodumene, which is a less densely packed form of the same mineral with a tetragonal crystal structure and specific gravity of 2.40 g/cm 3. The transformation leads to a volumetric expansion of around 30% ...

Extraction of lithium from spodumene - Murdoch

Spodumene is an important source of lithium, a key element of Li-ion batteries used in mobile communication and entertainment devices, hybrid and all electric cars and electric bikes. Spodumene forms three different crystal structures, the naturally occurred α- spodumene, and y and β-spodumene which are the products of heat treatment at 700 to 1100 °C.

Lithium (Li) - Properties, Applications

2013-7-11  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.
