Petalite is a rare lithium aluminum silicate mineral, often found in granitic pegmatites. It typically appears as colorless, white, or pale shades of pink and is known for its glassy luster. Petalite is primarily mined for its lithium content, which is essential for producing batteries and other electronic devices. This mineral has a unique crystal structure, forming in tabular or prismatic shapes. Due to its high melting point and low thermal expansion, petalite is also used in ceramics and glassmaking. Its occurrence is mainly in regions like Sweden, Brazil, and Australia, where it is often associated with other lithium-bearing minerals.
