description Spodumene Overview
Spodumene is a lithium aluminum silicate mineral in the pyroxene group, with the chemical formula LiAlSi2O6. It occurs in lithium-bearing pegmatites and is mined as an important source of lithium, which is used in products including rechargeable batteries, ceramics, and glass. Transparent crystals can be cut as gemstones: pink to lilac material is called kunzite, while green material is known as hiddenite; yellow spodumene is sometimes called triphane. The mineral is therefore relevant to both industry and gemology.
help Spodumene FAQ
What is the chemical formula of spodumene?
Spodumene has the chemical formula LiAlSi2O6. It is a lithium aluminum silicate mineral in the pyroxene group.
Why is spodumene important to the battery industry?
Spodumene is an important ore of lithium, a key material in many rechargeable batteries. Lithium from spodumene can be processed into battery chemicals such as lithium carbonate or lithium hydroxide.
Where does spodumene form?
Spodumene commonly occurs in lithium-bearing pegmatites, which are coarse-grained igneous rocks. These deposits can also contain other valuable minerals such as quartz, feldspar, and mica.
Can spodumene be used as a gemstone?
Yes. Gem-quality spodumene can appear as kunzite, usually pink to lilac, or hiddenite, commonly green. Color and clarity determine whether a specimen is treated as a gemstone or mined mainly for lithium.
