Abstract

Potassium tantalate was formed to pyrochlore structures on the tantalum substrate by hydrothermal or electrochemical method. In synthesizing process of potassium tantalate, a crystal structure of the substrate surface seemed to be an important factor. Potassium tantalate was synthesized with a simple equipment only, low temperature of 323 K or over, low concentration of 2–4 mol per liter potassium hydroxide aqueous solution and short time.
