Premium grade nitrate series and essential chemical salts direct from our state-of-the-art manufacturing plants.
Understanding the molecular dynamics, elementary structure, and chemical properties that make potassium nitrate an irreplaceable asset in high-tech industries.
Potassium Nitrate, denoted by the chemical formula $KNO_3$, is a crystalline ionic salt. To understand its unparalleled stability and high thermodynamic efficiency, we must examine its constituent components within the Periodic Table of Elements:
| Property Parameters | Industrial Grade Spec | Molten Salt Grade Spec |
|---|---|---|
| Molecular Weight | 101.103 g/mol | 101.103 g/mol |
| Appearance | White Free-flowing Powder | Ultra-pure Prills/Crystals |
| Assay ($KNO_3$ Purity) | ≥ 99.4% | ≥ 99.8% - 99.9% |
| Chloride ($Cl^-$) Content | ≤ 0.1% | ≤ 0.01% (100 ppm max) |
| Melting Point | 334 °C (633 °F) | 334 °C (633 °F) |
| Decomposition Temp | ~ 400 °C (752 °F) | ≥ 560 °C in binary mixtures |
| Moisture ($H_2O$) | ≤ 0.15% | ≤ 0.05% |
By optimizing the ratio of Group 1 cations ($K^+$ and $Na^+$) in molten mixtures, factories can adjust eutectic melting points down to $220^\circ\text{C}$, enabling efficient storage of solar thermal energy at scale without the risk of system solidifying.
How SHANXI VOJIN NEW MATERIALS CO., LTD. leverages geographical resources, raw materials, and processing technologies to deliver unmatched global value.
Our strategic placement in Shanxi Province grants us direct access to high-grade nitrogen sources and raw potassium chloride salts. The proximity of natural coal chemical reserves ensures integrated synthesis of nitric acid, eliminating high transportation overheads and raw material fluctuations.
We utilize the state-of-the-art metathesis (double-decomposition) reaction between ammonium nitrate and potassium chloride, followed by multiple fractional crystallization steps. This process successfully reduces sodium and chloride contaminants to record-low levels, critical for electronic-grade glass tempering and thermal storage.
With an annual output capacity of over 600,000 tons of molten salts and related chemical derivatives, Shanxi Vojin is engineered to fulfill bulk container orders dynamically. Our massive storage facilities minimize delivery lead times even during seasonal shipping peaks.
Our core manufacturing programs organized by industrial categories. Highly purified, reliable, and packaged for overseas transport.
Every product line is scrutinized under strict ISO 9001:2015 quality control parameters. Our inorganic chemicals line includes high-purity nitrate salts tailored specifically for high-stress applications.

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. Officially established with an expanded production baseline in 2010, we have systematically engineered solutions that power green energy storage and high-yielding agriculture.
Our years of manufacturing experience and refined products provide you with better performance, lower system corrosion, and optimized thermal efficiency.
Securing cross-border chemical shipping involves navigating rigorous safety profiles, custom mandates, and local environmental standards.
As an oxidizing chemical compound (UN Number: 1486, Hazard Class: 5.1), Potassium Nitrate requires specialized export documentations and certified transport workflows. Vojin New Materials ensures all shipments align with key international regulations:
We work with international logistics providers to support DDP, CIF, and FOB delivery configurations. Our domestic transport routes connect directly with major ocean shipping hubs in Northern and Eastern China, including Tianjin Port and Qingdao Port, which feature certified Dangerous Goods container loading facilities.
Additionally, we supply custom labels in Spanish, German, French, and Japanese to satisfy local hazard communication requirements (GHS / OSHA HCS standards).

Navigating the global shift toward decarbonization, high-performance molten salts, and precision agriculture.
Thermal Energy Storage (TES) technologies are undergoing massive expansions to balance the electrical grid's solar and wind variability. Molten salt, consisting of a binary blend of 60% sodium nitrate and 40% potassium nitrate, remains the gold standard for high-temperature heat transfer. Due to its broad operating temperature range (from $290^\circ\text{C}$ to over $560^\circ\text{C}$), it absorbs immense quantities of heat during peak solar hours and drives steam turbines long after sunset.
Modern R&D efforts focus on reducing impurities like chloride and sulfate ions below 50 ppm, which drastically lowers the degradation rate of storage tanks and piping, extending concentrated solar plant lifespans past 30 years.
The consumer electronics market demands increasingly rugged and thin cover glasses. Chemical strengthening utilizes a potassium-for-sodium ion exchange process. Immersing silica glass in a bath of molten potassium nitrate ($KNO_3$) causes $K^+$ ions (with larger ionic radii) to replace smaller $Na^+$ ions on the glass surface.
This exchange creates high compressive stress on the glass surface layer, providing high scratch resistance and impact protection for smartphone screens and aerospace dashboards.
