Work at Lilypad in 2001-2002 focused on defining tantalum resources, but was also successful in identifying widespread occurrences of the cesium ore mineral pollucite in a field of highly fractionated lithium-cesium-tantalum pegmatite dykes. In October 2020, Avalon carried out a short field program to collect 200 kilograms of cesium mineralized ...
Potassium heptafluorotantalate is an intermediate in the industrial production of metallic tantalum. Its production involves leaching tantalum ores, such as columbite and tantalite, with hydrofluoric acid and sulfuric acid to produce the water-soluble hydrogen heptafluorotantalate. [2] Ta 2 O 5 + 14 HF → 2 H 2 [TaF 7] + 5 H 2 O
Treatment of tantalum pentachloride with hexamethylbenzene (C 6 Me 6), aluminium, and aluminium trichloride gives [M(η 6-C 6 Me 6)AlCl 4] 2. [7] Tantalum-alkyne complexes [8] catalyze cyclotrimerizations. [9] [10] Some tantalum-alkyne complexes are precursors to allylic alcohols. [11] Tantalacyclopropenes are invoked as intermediates.
