Unfortunately for Ekeberg, in 1809 the well-known English chemist Willian Wollaston said there had been no discovery and there was no new element. The chemical symbol for tantalum is Ta. Tantalum is used to make components for chemical plants, nuclear power plants, airplanes and missiles. It’s tough but malleable and can be drawn into fine wire. In many cases, their supplies are actually abundant, but they can be both difficult and expensive to process. 0. 4.8 out of 5 stars 16.
