What is "tantalate"

Tantalate \Tan"ta*late\, n. (Chem.) A salt of tantalic acid.

n. (context chemistry English) any salt of tantalic acid

Tantalate is an tantalum-containing anion or a salt of such an anion. A commercially important example is heptafluorotantalate (TaF) and its potassium salt (KTaF).

Many oxides of tantalum are called tantalates. They are viewed as derivatives of "tantalic acid", hypothetic compounds with the formulas TaO·nHO or HTaO). Examples of such tantalates are lithium tantalate (LiTaO), lutetium tantalate (LuTaO) and lead scandium tantalate (PST or Pb( Sc Ta) O. Polyoxometallates containing tantalum provide examples of discrete tantalum oxides that exist in solution.
