Abstract—. We have synthesized and investigated sodium sulfate-based materials with Na + ion conductivity: Na 2 SO 4, Na 2 SO 4:3.5% Yb, and Na 3 Ga(SO 4) 3.The addition of Yb 3+ heterovalent cations leads to a considerable increase in the electrical conductivity of Na 2 SO 4 (by ~240 times at 573 K) as a result of sodium …
