Name: MgO-Doped β″-Al₂O₃ Sodium-Ion Solid-State Electrolyte (β″-Al₂O₃-MgO)
Material Form: White powder
Product Code: XN-NaBA-MgO
Description:
MgO-doped β″-Al₂O₃ is a beta-double-prime sodium aluminate ceramic solid-state electrolyte engineered for sodium-ion (Na-ion) and sodium-sulfur (Na-S) battery research. The introduction of MgO doping into the β″-Al₂O₃ lattice substitutes Al³⁺ sites and increases mobile Na⁺ concentration, dramatically enhancing both ionic conductivity and thermal stability. As a result, the material exhibits excellent room-temperature performance (>0.1 mS/cm) and outstanding high-temperature conductivity (0.2 S/cm at 300 °C), making it the standard choice for high-temperature sodium battery systems.
Application:
This material serves as a sodium-ion conducting solid electrolyte and separator for sodium-sulfur (Na-S) batteries, sodium-metal halide (ZEBRA) batteries, sodium-ion battery research, and high-temperature electrochemical cells. Furthermore, it is widely used in academic studies of fast Na⁺ ion transport mechanisms and ceramic electrolyte processing.

Characteristics:
High-temperature ionic conductivity (0.2 S/cm at 300 °C)
The 300 °C conductivity reaches 0.2 S/cm — sufficient to support practical high-temperature sodium battery operation including Na-S and ZEBRA cells. Moreover, the material maintains stable performance across multiple thermal cycles.
MgO doping enhances Na⁺ transport
Substituting Al³⁺ with Mg²⁺ creates additional charge-balancing Na⁺ vacancies in the conduction plane. As a result, both Na⁺ concentration and ionic mobility increase, lifting overall conductivity above undoped β″-Al₂O₃.
Improved thermal stability
MgO doping suppresses unwanted phase transitions during high-temperature operation. Therefore, customers can use the material reliably in cyclic high-temperature applications without degradation of the conductive layered structure.
Trigonal layered crystal structure
The β″-Al₂O₃ lattice provides two-dimensional Na⁺ conduction pathways within the spinel-block-separated layers. Consequently, ion transport is rapid and anisotropic, which is the foundation of this material’s high conductivity.
Packaging & Storage:
The material ships in a glass bottle, then vacuum-sealed in an aluminum-plastic bag. Therefore, customers should store it sealed in a dry environment, protected from moisture. Reseal promptly after opening. Sealed shelf life is 1 year.
Safety:
For research and industrial use only. Wear PPE (gloves, masks, safety goggles) when handling powders. Refer to SDS for complete safety information.
Note: Values listed above are typical and for reference only. Performance may vary depending on cell architecture, temperature, and test protocol. For other sodium-ion solid electrolytes, see our Na₃PS₄ Sodium-Ion Sulfide Solid-State Electrolyte and NASICON NZSPO Sodium-Ion Electrolyte.
