Discover our certified, high-grade chemical materials manufactured under global quality standards.
Potassium Nitrate ($KNO_3$) acts as a key element in advanced industries, ranging from concentrated solar power (CSP) generation to glass strengthening and high-yield agriculture. As a compound with oxidation characteristics, safety in production, handling, and supply chains is essential for enterprise operations. Shanxi Vojin New Materials Co., Ltd. addresses these challenges by introducing a comprehensive system that aligns chemical purity with safety and reliability.
Our focus is on managing trace impurities, particularly chloride and sodium ions, to protect processing equipment from high-temperature corrosion. By combining chemical synthesis with safety protocols, we supply industrial materials that meet international standards (including REACH, RoHS, and standard IMDG shipping codes).
With an annual production capacity of 600,000 tons of molten salts and related nitrates, Vojin serves the global market as a reliable manufacturer. We deliver stable chemical solutions that minimize downtime and support operational continuity for our partners.
The chemical engineering behind Vojin's ultra-pure, anti-caking potassium nitrate crystals.
We refine the metathesis reaction between Ammonium Nitrate ($NH_4NO_3$) or Sodium Nitrate ($NaNO_3$) and high-grade Potassium Chloride ($KCl$). Multi-stage vacuum crystallizers use controlled temperature profiles to separate sodium chloride and achieve high purity $KNO_3$ precipitation.
For electronic glass and solar-grade applications, our ion-exchange purification columns extract trace divalent metallic ions. This step reduces iron, magnesium, and calcium levels to the parts-per-million (ppm) range, limiting catalytic decomposition in high-heat systems.
To prevent product hardening during sea transit, we use organic and inorganic anti-caking coatings. These surface treatments maintain flowability in varying humidity levels without affecting solubility or chemical compatibility.

Shanxi Vojin's production facilities integrate DCS (Distributed Control Systems) to manage the entire manufacturing process. From raw material intake to crystallization and final packaging, automation ensures consistent chemical and physical properties across batches.
Located in Shanxi, the center of China’s inorganic chemical industry, we benefit from a stable supply of key minerals, including potassium salts and nitric acid. This localized supply chain insulates our operations from raw material volatility and supports reliable pricing and lead times for our clients.
We employ real-time monitoring and off-gas scrubbers to meet domestic environmental regulations. These systems help prevent production pauses during peak seasons, allowing us to maintain stable, year-round output.
Delivering chemical performance across critical global industries.
Established in 2010 with foundations dating back to 2000, Shanxi Vojin New Materials Co., Ltd. has developed into a reliable provider of thermal energy storage salts and water-soluble fertilizers.
Our team focuses on research and development to improve the purity, physical integrity, and handling safety of chemical compounds. We work with partners in over 40 countries to deliver consistent materials for demanding industrial processes.
