High-purity chemical compounds engineered for industry-leading thermal storage and precision agriculture
Decoding the chemical thermodynamics and high-purity parameters of industrial KNO3
Potassium Nitrate (KNO3), designated under PubChem CID 24434, represents one of the most chemically stable and thermophysically efficient compounds in modern industrial chemistry. With a molecular weight of 101.103 g/mol, a melting point of approximately 334°C, and decomposition threshold starting at 400°C, high-purity potassium nitrate stands as an essential component across multiple advanced industries. From its key role in Concentrated Solar Power (CSP) thermal storage systems to its high-solubility performance in modern agricultural fertilizers, the substance plays a vital part in the transition toward clean energy and sustainable farming.
As leading manufacturers, Shanxi Vojin New Materials Co., Ltd. produces potassium nitrate that adheres strictly to global industrial and pharmaceutical standards. Our production processes minimize structural impurities, such as sodium, chlorides, and heavy metals, ensuring that our products achieve outstanding electrical and thermal conductivity. Whether deployed as a solid-state oxidizer or integrated into binary molten salt formulations, our chemical profiles match or exceed the standard benchmarks recorded in the PubChem compound registry.
Our potassium nitrate features an orthorhombic crystal structure at room temperature, transforming into a trigonal system at 129°C. This phase change is managed to maintain stability during handling, bulk storage, and blending.
Exhibiting high heat capacity in the liquid phase, our KNO3 serves as a reliable thermal medium for energy storage, maintaining low corrosion rates when in contact with stainless steel container systems.
Our agricultural-grade potassium nitrate dissolves completely in water (133 g/L at 0°C, scaling to 2470 g/L at 100°C), making it suitable for modern drip irrigation and foliar feeding applications.
Founded with a commitment to chemical innovation, Shanxi Vojin New Materials Co., Ltd. has grown into a major supplier of inorganic salts, molten energy storage media, and high-performance fertilizers. Over fifteen years of development, we have established advanced production facilities that serve industrial operations across the globe. Our company values precision, safety, and sustainable chemical processes.
Operating from our 1,000-acre manufacturing site, we run automated production lines that keep product consistency high and impurities low. We serve customers in more than forty countries, delivering solutions tailored to the needs of the molten salt energy market, high-yield agriculture, and industrial manufacturing.
Strengthening infrastructure, green energy, and global food security with high-purity chemical manufacturing
Concentrated Solar Power (CSP) plants rely on binary salt mixtures containing high-purity potassium nitrate. Our low-sodium, low-chloride formulations protect piping from corrosion and ensure efficient heat transfer at operational temperatures up to 565°C.
Used in chemical strengthening processes for high-durability cover glass, our potassium nitrate facilitates ion-exchange (replacing sodium ions with larger potassium ions). This treatment increases structural strength for consumer electronics and industrial displays.
As a chloride-free source of potassium and nitrogen, our KNO3 supports balanced crop nutrition. It improves osmotic regulation, cold resistance, and yield quality in high-value fruits, vegetables, and flowers.

From KNO3 and NaNO3 to specialized water-soluble fertilizers, we provide a variety of inorganic compounds to meet diverse manufacturing requirements.
Meeting international standards for chemical logistics, safety, and environmental protection
Potassium Nitrate is classified as an oxidizer (UN Number 1486, Hazard Class 5.1). Transporting and storing it requires compliance with the International Maritime Dangerous Goods (IMDG) code, US DOT regulations, and European REACH directives.
Our packing options include double-layered moisture-proof PP bags (25kg, 50kg, and 1000kg bulk bags) designed to prevent environmental exposure and ensure product stability during transport. Every shipment is accompanied by a complete Safety Data Sheet (SDS) aligned with GHS standards.
To maintain the properties registered under PubChem CID 24434, potassium nitrate must be stored in cool, dry, well-ventilated warehouses. It should be kept away from organic materials, reducing agents, strong acids, and heat sources.
Our quality control program conducts laboratory testing on every production batch. We verify chemical purity, particle size distribution, and trace mineral levels, ensuring the material meets specified parameters before dispatch.

Technical specifications, ordering information, and logistics details for wholesale buyers
Molten-salt-grade Potassium Nitrate requires strict control over impurities like chloride (Cl-) and sodium (Na+) ions. Standard specifications demand a KNO3 purity of ≥99.7% or ≥99.8%, with chloride content kept below 0.01% (100 ppm) and moisture below 0.05%. Reducing these impurities minimizes high-temperature corrosion on the stainless steel heat exchangers and containment vessels used in thermal storage facilities.
Agricultural grades focus primarily on nutrient availability, typically specifying 13% Nitrogen (all-nitrate nitrogen) and 46% Potassium (as K2O), with a higher tolerance for trace elements.
Our quality control system uses automated process monitoring, from raw material inspection through crystallization to final packaging. Each production batch undergoes laboratory testing using Inductively Coupled Plasma (ICP) spectroscopy and ion chromatography to verify elemental purity. We provide a Certificate of Analysis (COA) for every shipment, documenting compliance with agreed technical specifications.
Under international transportation codes (such as IMDG and DOT), Potassium Nitrate is classified as an Oxidizing Agent (Class 5.1, UN 1486, Packing Group III). Cargo handling and shipping documents must comply with hazardous material regulations. We package our products in GHS-compliant, heavy-duty, double-layered woven bags to prevent physical damage and keep moisture out during transport.
Typical lead times for standard wholesale orders range from 15 to 25 days from contract confirmation, depending on volume, packaging choice, and shipping destination. Our export team coordinates customs declarations, vessel scheduling, and inland transport to ensure on-time delivery. We also offer customization for packaging specifications and particle size distribution to meet particular operational needs.
