Solid electrolytes compositions, methods of making the solid electrolytes, and methods of using the solid electrolytes in batteries and other electrochemical technologies are disclosed. The method of producing a solid electrolyte comprises (a) ball milling Na2CO3, SiO2, NH4H2PO4, a zirconium source, and a dopant to produce a ball milled powder; (b) calcining the ball milled powder to produce a calcined powder; and (c) sintering the calcined powder to produce a solid electrolyte. The zirconium source for the solid electrolyte may be ZrO2. The dopant for the solid electrolyte may be AI2O3, Fe2O3, Sb2O3, Yb2O3, or Dy2O3.
