What is Tantalum Organic Complex Compound

The most important of tantalate is potassium and sodium salts.
Potassium tantalate has K 2O:Ta2O 5 from 3:7 to 10:3. The most common stable tantalate is potassium tantalate (K2O.Ta 2O 5); six potassium tantalate (4K2O.3Ta 2O 5). Tantalum potassium salt is soluble in water, but partial salt solubility is smaller, KTaO 3 at 25 DEG C when the solubility is 4.87 * 10-5mol/L.

Sodium tantalate has Na 2O:Ta2O 5 as 4:3, 7:5, 1:1, 1:3 and 2:7, such as NaTaO 3, Na 5TaO 5, 4Na 2O. It is 5. yuan. The solubility of sodium in water and caustic soda solution is very small, the solubility of 25 C NaTaO 3 salt is 5.5 * 10-5mol/L.

Tantalum organic complex compound
The tantalum complex is mainly tannic acid, its color is lemon yellow, and it is precipitated from weak acidic solution (pH=3~4) after boiling.

Tantalum alkoxide

Tantalum alkoxide quinquevalent is highly volatile, these alkoxides can be without distillation under the pressure of 6.67~1333Pa. The boiling point of tantalol is influenced by the length of the chain.
