Premium grade molten salts, nitrates, and specialty chemical compounds engineered for high thermal efficiency and precision agriculture.
Molten salt formulations, typically consisting of binary eutectic mixtures like 60% Sodium Nitrate (NaNO3) and 40% Potassium Nitrate (KNO3), play a critical role as heat transfer fluids (HTFs) and thermal energy storage (TES) media. However, due to their strong oxidizing properties, these compounds are classified under the International Maritime Dangerous Goods (IMDG) Code as Class 5.1 Oxidizing Substances (typically UN 1486 for Potassium Nitrate and UN 1498 for Sodium Nitrate).
Navigating the supply chain for Class 5.1 DG goods requires rigorous adherence to global compliance standards, special packaging, and specialized logistics management. As a premier manufacturer and supplier, Shanxi Vojin New Materials Co., Ltd. implements state-of-the-art safety controls to prevent contamination, cross-reactions, and thermal hazards during manufacturing, containerization, and intercontinental transit. Our production process eliminates trace organic matter, minimizing risk and optimizing safety metrics for global shipments.
By enforcing strict separation protocols and utilizing moisture-resistant, multi-layered polypropylene bags with PE liners, we ensure that our materials remain dry and stable. This structural integrity guarantees that when our products reach Concentrated Solar Power (CSP) plants or industrial thermal facilities, they perform with zero initial degradation, maximizing the operational lifespan of the energy storage systems.
Our technical team coordinates with certified marine surveyors and custom authorities to expedite DG logistics clearance.

Read Case Study →High-purity potassium nitrate facilitates potassium-sodium ion exchange at temperatures up to 450°C, hardening display screens for electronics.
Technical Details →Assists in heat transfer networks, waste heat recovery, and coal conversion plants, reducing system corrosion and optimizing thermal conversion.
Explore Applications →Highly soluble nitrates supply active nitrogen and potassium to crops, enhancing yield, supporting crop resilience, and feeding smart greenhouse irrigation systems.
Fertilizer Guide →In modern industrial procurement, securing a consistent supply of raw, high-purity inorganic nitrates is key to operational stability. Over the past decade, global demands have pivoted towards supplier options that guarantee low impurity profiles (particularly with chlorides and sulfates) to minimize equipment wear. High chloride levels in molten salts accelerate the oxidation of stainless steel tanks, generating pitting corrosion that can lead to catastrophic systems failure.
Shanxi Vojin New Materials Co., Ltd. leverages a highly strategic geographic position in Shanxi Province, China, a global epicenter for coal-chemical processing and raw inorganic synthesis. Our access to direct raw materials enables us to insulate international buyers from supply bottlenecks and pricing volatility. We operate close-looped production lines capable of turning out 600,000 metric tons of molten salts annually.
Furthermore, our operations maintain rigorous testing protocols at every stage, from material input to delivery. Utilizing Inductively Coupled Plasma (ICP) spectroscopy and Ion Chromatography, our laboratory technicians monitor critical impurities down to single-digit parts per million (ppm). This comprehensive quality assurance structure ensures our industrial products meet the demands of global EPC contractors and industrial distributors.
Driven since 2000, we have been committed to the entrepreneurial spirit and passion for innovation. Our team takes pride in delivering dependable products and services with a quality distinction in the thermal energy storage & water-soluble fertilizer industries globally. Our corporate headquarters and advanced facilities sit in Shanxi, China, allowing us to utilize natural regional resource synergies to manufacture extremely high-purity chemical salts at competitive scales.
Our focus centers on optimizing the purity of potassium nitrate, sodium nitrate, and calcium-based salts. By lowering total contaminants, we increase safety metrics and help our customers lower their maintenance overhead. Whether you are engineering a multi-megawatt Concentrated Solar Power facility or formulating performance agricultural feeds, Vojin New Materials stands ready as your primary production partner.

The global push for green grid integration and zero-carbon industrial heat has propelled molten salts into the spotlight of energy transition technologies. Next-generation systems are shifting away from traditional solar salts to find compounds with broader operating temperatures. Expanding the liquid temperature envelope—specifically lowering the melting point below 140°C while maintaining thermal stability up to 600°C—remains a major R&D focus.
By blending ternary or quaternary eutectic salt mixtures including calcium nitrate, researchers can lower the freeze point of the salt solution significantly. This development dramatically decreases parasitic heating costs at CSP and thermal plants. Our R&D division at Vojin New Materials works alongside energy laboratories to refine these ternary mixes, helping to optimize system start-up times and eliminate risk of pipeline freeze-up.
Equally critical is the development of non-corrosive additive packages. Trace contaminants, even under 0.05%, alter molten salt behavior at high temperatures. Our chemical engineers develop specialized crystallization procedures that systematically separate and remove reactive chlorides and carbonates, improving overall heat exchanger reliability and offering our clients significant lifetime savings.
