Cesplumtantite is a tetragonal, colorless mineral, containing tin, tantalum, sodium, oxygen, niobium, lead, cesium, calcium, and antimony. The mineral was first discovered in 1986 from Manono in Shaba, Zaire. It was named after the presence of tantalum, plumium (lead), and cesium in its composition. Properties of Cesplumtantite.
Cesplumtantite is a mineral with formula of Cs 2 Pb 2+ 3 Ta 5+ 8 O 24 or Cs 2 Pb 3 Ta 8 O 24. The corresponding IMA (International Mineralogical Association) number is IMA1985-040. The IMA symbol is Cptan.
