General description

Sodium chloride, anhydrous is a colorless crystalline inorganic compound highly soluble in water. Our Sodium chloride anhydrous,is suitable molten salt to prepare different types of eutectic mixtures due to its high operation temperature for thermal energy storage (TES) materials and heat transfer fluids (HTFs) for next-generation concentrating solar power (CSP) systems.
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product belongs to an Enabling category, and is crucial in molten salt mixtures for thermal energy storage in concentrating solar power systems. Its low cost and effective thermal properties enhance energy storage efficiency, supporting renewable energy use and reducing environmental impact. Click here for more information.

Application

Molten chloride salts are considered favorable for Concentrated Solar Power (CSP) applications due to their exceptional thermal properties and high decomposition temperatures. The corrosion behavior of Inconel 625 and Hastelloy B-3 alloys was studied in a molten salt environment comprising NaCl-CaCl2-MgCl2. Other studies have documented the development of an in situ corrosion and mass transport monitoring method that utilizes a radionuclide tracing technique for studying the corrosion of 316L stainless steel (316L SS) in a NaCl–MgCl2 eutectic molten salt natural circulation loop. The eutectic salt used in this study was prepared with 58.5 mol% anhydrous sodium chloride and 41.5 mol% anhydrous magnesium chloride.
Furthermore, various MAX phases and Lewis acid salts were employed in the preparation of MXenes using the molten salt synthesis method. For example, Ti3SiC2 MAX phase and CuCl2 were mixed in a stoichiometric molar ratio of 1:3, along with sodium chloride , anhydrous and Potassium chloride, anhydrous. The mixture was heated to 750 °C and held for 24 h in an argon atmosphere. After washing with deionized water, MXene/Cu mixed particles were obtained, followed by further cleaning with APS solution, deionized water, and alcohol. The resulting MXene powders ( MS-Ti3C2Tx) were dried under vacuum at room temperature for 24 h.

Our Sodium chloride which is anhydrous, with a purity of ≥99.99%, is an excellent choice for molten salt synthesis method. Its anhydrous properties and high purity make it highly suitable for thermal energy storage (TES) materials and heat transfer fluids (HTFs) for next-generation concentrating solar power (CSP) systems and molten salt reactors (MSR).
