CAS 1302-66-5

Petalite (AlLi(Si2O5)2)

Description:

Petalite, with the chemical formula AlLi(Si2O5)2 and CAS number 1302-66-5, is a lithium aluminum silicate mineral that typically occurs in a colorless to white or pale pink form. It is characterized by its monoclinic crystal system and is often found in granitic pegmatites. Petalite has a relatively low hardness on the Mohs scale, typically ranging from 6 to 6.5, and exhibits a vitreous to pearly luster. Its specific gravity is moderate, generally around 2.4 to 2.5. Petalite is notable for its high lithium content, making it an important source of lithium for various applications, including batteries and ceramics. Additionally, it has a low thermal expansion coefficient, which contributes to its stability under heat. The mineral is also used in the production of glass and porcelain due to its ability to improve the thermal and mechanical properties of these materials. Overall, petalite is valued both for its industrial applications and its role in the geology of lithium-rich environments.
