An in-depth analysis of high-temperature thermal storage agents and high-purity inorganic nitrates in modern engineering.
As the global industrial landscape transitions toward deep decarbonization, thermal energy storage (TES) has emerged as a cornerstone for integrating intermittent renewable power. Molten salts—particularly binary blends of sodium nitrate (NaNO₃) and potassium nitrate (KNO₃)—serve as the preferred heat transfer fluids (HTFs) and storage media for Concentrated Solar Power (CSP) plants, industrial steam production, and grid-scale waste heat recovery systems.
Procurement teams at global utility firms and EPC (Engineering, Procurement, and Construction) companies look for long-term supply stability and strict chemical purity from Chinese manufacturers. Small variations in moisture content or impurity levels (such as chloride and sulfate ions) can cause accelerated equipment corrosion, block pipelines, and reduce thermal efficiency. Consequently, purchasing agents require certified chemical composition reports, reliable anti-caking properties, and specialized shipping methods to handle transoceanic shipping conditions.
The performance of molten salt thermal energy storage relies directly on the purity of the chemical compounds. Binary solar salt mixtures (typically 60% NaNO₃ and 40% KNO₃ by weight) must operate reliably within a thermal window of 290°C to 565°C. Impurities must be strictly limited to prevent premature chemical decomposition at higher temperatures:

How we address corrosion, raw material purity, and anti-caking challenges for international shipping.
One of the primary challenges in molten salt applications is corrosion. Chloride ($Cl^-$) and sulfate ($SO_4^{2-}$) impurities accelerate the oxidation of stainless steel and alloy pipelines inside salt tanks. Shanxi Vojin New Materials limits chloride content to less than 0.01%, extending the service life of industrial storage vessels and reducing project maintenance costs.
We also study the thermal stability parameters of salt mixtures. In high-temperature operations, sodium nitrate can slowly convert to sodium nitrite, releasing oxygen. To manage this thermal equilibrium, our R&D department uses specific oxide stabilizers that support continuous operation up to 600°C, helping plant operators maximize thermodynamic efficiency.
Industrial nitrates are naturally hygroscopic and prone to caking during ocean transit. Caked salts require crushing at the job site, which delays projects and increases costs. Vojin addresses this issue using two methods:
