The material ships vacuum-sealed under an inert atmosphere in moisture-barrier aluminum-laminated bags. Therefore, customers should store it sealed in an Ar or N₂ glovebox or dry room, protected from moisture. Because NaTaOCl₄ is a sodium tantalum oxychloride solid electrolyte, avoid prolonged exposure to humid air and handle it in a dry environment. Reseal promptly after opening.
For research and industrial use only. Avoid inhalation of dust and contact with eyes, skin, or clothing. Wear PPE (gloves, safety goggles, and lab coat); use local exhaust ventilation and suitable respiratory protection when dust may be generated. Avoid exposure to water and humid air. Refer to SDS for complete safety information.

This material is a moisture-sensitive halide solid-state electrolyte powder requiring inert atmosphere handling. Storage and usage must follow strict protocols to prevent degradation from ambient humidity.
- Moisture Sensitivity: The material is delivered with a measured moisture content of 13.8 ppm and must be protected from atmospheric moisture to maintain its electrochemical properties.
- Inert Atmosphere Storage: Store the sealed bag in an argon or nitrogen glovebox or a dry room with controlled humidity.
- Reseal After Opening: Reseal the moisture-barrier bag promptly after each use to prevent moisture ingress.
- Personal Protective Equipment: Wear appropriate PPE including gloves, safety goggles, and lab coat when handling the powder to avoid dust contact.
- Avoid Dust Inhalation: Use local exhaust ventilation or respiratory protection if dust may be generated during handling.
What is the measured ionic conductivity of NaTaOCl4 at 26.0 °C and how does its extremely low electronic conductivity impact its function as a solid electrolyte?
The measured ionic conductivity of NaTaOCl4 is 2.51 mS/cm at 26.0 °C, while its electronic conductivity is only 3.13 × 10⁻¹⁰ S/cm at 25.2 °C. This 10⁷-fold difference confirms that the material is a predominantly ionic conductor, minimizing internal short-circuit risks in solid-state batteries.
What is the moisture content of NaTaOCl4 and how should it be handled to maintain its electrochemical properties?
The measured moisture content is 13.8 ppm, indicating a very dry material. It must be stored vacuum-sealed under inert atmosphere in moisture-barrier aluminum-laminated bags and handled in an Ar or N₂ glovebox or dry room to prevent moisture uptake, which would degrade ionic conductivity and cause decomposition.
What are the recommended storage conditions and safety precautions for NaTaOCl4 in a research laboratory?
Store NaTaOCl4 sealed in moisture-barrier aluminum-laminated bags under inert atmosphere (Ar or N₂ glovebox). Avoid exposure to water and humid air. Use PPE including gloves, safety goggles, and lab coat, with local exhaust ventilation. Refer to SDS for complete safety information.
NaTaOCl4 (NTOC) is a sodium tantalum oxychloride halide solid-state electrolyte with a measured ionic conductivity of 2.51 mS/cm at 26.0°C and an electronic conductivity of 3.13×10⁻¹⁰ S/cm, indicating good ionic selectivity for all-solid-state battery research. Its low moisture content (13.8 ppm) and fine particle size (3.87 μm D50) support electrolyte formulation and interface studies, but the material requires inert-atmosphere handling due to moisture sensitivity.
Positive
- High ionic conductivity for sodium electrolyte: Measured ionic conductivity of 2.51 mS/cm at 26.0°C is competitive for sodium-based halide solid electrolytes, enabling efficient ion transport in all-solid-state battery cells.
- Low electronic conductivity and moisture content: Electronic conductivity of 3.13×10⁻¹⁰ S/cm at 25.2°C indicates minimal leakage current, while 13.8 ppm moisture content confirms low water uptake, supporting reliable electrochemical characterization.
Trade-offs
- Moisture-sensitive handling required: The material must be stored and handled in an inert atmosphere (Ar or N₂ glovebox or dry room) to prevent degradation from humid air, adding infrastructure requirements for laboratory use.
- Fine particle size may complicate processing: With a D50 of 3.87 μm and specific surface area of 19.774 m²/g, the powder may require careful dispersion and compaction techniques to achieve uniform films or pellets in electrolyte fabrication.
