• 개요

  Petalite has the chemical formula LiAlSi4Oi0 . Petalite theoretically contains 2.27% lithium (4.88% lithia) but in nature contains about 1.8% lithium (3.5-4.5% lithia). The mineral is found in Sweden, South-west Africa and southern Rhodesia. Petalite is presently used as a source of lithium in glasses and glazes and as a low-expansion filler in refractories.
  

• 화학적 성질

  Petalite, LiAlSi4O10, is a monoclinic mineral with a framework silicate structure. It is grayish white in color and occasionally has a pinkish hue. The mineral has two cleavage directions, which form an angle of 38.5°. The basal cleavage is perfect.

• 물리적 성질

  Petalite is a lithium sodium aluminum silicate with a hardness of 6 to 6.5. It belongs to the monoclinic crystal system. This mineral crystallizes relatively rarely and is commonly found in the form of large, cleavable masses. Petalite can exhibit various colors including white, colorless, gray, pinkish, or yellow. Colorless specimens can be cut into exceptionally brilliant gemstones and some can be shaped into cats-eyes. Petalite typically forms within granite pegmatites and is often found in association with other lithium-containing minerals such as Amblygonite, Kunzite, Spodumene, and Lepidolite. It is primarily sourced from Australia, Brazil, Sweden, Namibia, and Afghanistan.
