A compound, identified by X‐ray diffraction analysis as sodium metatantalate (Na 2 Ta 2 O 6 ), was found at the interface between a sodium silicate glass and tantalum metal which had been heated in vacuum to 1000°C. Thermodynamic calculations, followed by further experimental evidence, were used to determine the chemical reaction between tantalum and sodium silicate which resulted in the formation of Na 2 Ta 2 O 6 . The compound was synthesized by other methods and its structure was investigated.
