Conclusions

A study was made of the resistance of tantalum germanides to the action of some liquid aggressive media and atmospheric oxygen. It is shown that tantalum germanides are fairly resistant to attack by various acids and their mixtures, but react with solutions containing fluorine ions, Perhydrol, and concentrated sulfuric acid. Their resistance to the action of liquid reagents grows with rise in their tantalum content. A study was made also of the atmospheric oxidation resistance of the germanides at various temperatures.
