| 释义 |
Tantalate is an tantalum-containing anion or a salt of such an anion. A commercially important example is heptafluorotantalate (TaF72−) and its potassium salt (K2TaF7). Many oxides of tantalum are called tantalates. They are viewed as derivatives of "tantalic acid", hypothetic compounds with the formulas Ta2O5·nH2O[1] or HTaO3[2]). Examples of such tantalates are lithium tantalate (LiTaO3), lutetium tantalate (LuTaO4) and lead scandium tantalate (PST or Pb(ScxTa1-x)O3. Polyoxometallates containing tantalum provide examples of discrete tantalum oxides that exist in solution.
