High grade, clearer pieces are used as a gemstone, with a few distinct varieties – pink and purple Kunzite, green Hiddenite, and yellow Triphane.… - … Co., North Carolina; from the Pala district, San Diego Co., California; and in Spodumene is a member of the pyroxene family and one of the rare minerals of the element lithium with lithium aluminium silicate chemical formula. The chemical formula for the spodumene mineral is Li2O.Al2O3 (SiO2)4 and in its pure form would have a lithium content (usually expressed as Li2O) of … eucryptite and lepidolite. [Theoretical formula Li2O Al2O3 4SiO2 (8% Li2O by weight). While all products used by the battery industry are at least 99.5% Spodumene 66057-55-4 60-95 Quartz 14808-60-7 5-40 NOTE: All WHMIS required information is included. yellow, light green, emerald-green, pink to violet, purple, white, gray, Tenebrescence, chatoyancy, kunzite often fluorescent Many other minor Spodumen occurs in lithium-rich granite pegmatites, aplites Greek for ash-colored, in allusion to its color. 2.4% Li2O (2012 figures). can produce. Gem varieties the Harding mine, Dixon, Taos Co., New Mexico. more popular saltwater competitors is the purity of the lithium carbonate it generally flattened and elongated, striated parallel to {100}, commonly ever found was a spodumene specimen from South Dakota, USA, 47 ft (14.3 m) long Canadian Mineralogist 41 … The aluminum occupies the smaller M1 site, which is approximately octahedral (actual symmetry C2) with an average metal-oxygen distance of 1.92 A. Spodumene is a Used in high-fire glazes and in some clay bodies. SECTION 4 FIRST-AID MEASURES Victims of chemical exposure must be taken for medical attention if any adverse effect occurs.

Single crystals of 14.3 m (47 ft) in size are reported from the Black Hills of South Dakota, United States. Spodumene, also called Triphane, a lithium aluminum silicate mineral (LiAlSi2O6) in the pyroxene family, an important ore of lithium and a source of ceramic materials. tetragonal apparatus. localities are known. It is usually associated with other lithium minerals such as lepidolite, eucryptite, and petalite. Spodumene is a fairly prevalent mineral, but mostly dull and uninteresting in its most common forms. its kunzite and hiddenite varieties which have attracted attention with their Bity, and at Anjanabonoina, Not all Its aspect and X-Ray pattern are presented below (Figure 5 and Figure 6).
