化学的特性Cassiterite is a tin oxide mineral with a hardness of 6 to 7. Its name is derived from the Greek word for tin. It has a tetragonal crystal system and can be found in short, prismatic crystals, though it is more commonly found in massive, granular, radiated, fibrous, or botryoidal forms. It has an adamantine to metallic luster and its color ranges from reddish brown to brownish black, with occasional colorless specimens. While cassiterite can be cut into gems, high-quality pieces are rare. It has been discovered in Australia, Bolivia, Mexico, Malaysia, England, and Namibia.

応用分野

解説錫石，スズの最も重要な鉱石。化学組成SnO2。正方晶系。通常は短柱状。放射同心構造の微細結晶の集合体は木スズ石と呼ばれる。もろい。黄褐色，赤褐色，黒褐色で，ダイヤモンドないし金属光沢。モース硬度6～7。比重6.99。条痕は白色，灰色，褐色。スズ石は花コウ岩，ペグマタイト，接触交代鉱床，熱水鉱床などに少量含まれているが，含スズ花コウ岩がマレーシア，インドネシアなどの高温多湿地域で風化し大規模なスズ石の砂鉱床を形成している。
