As Australia gears up to transform its energy architecture to achieve net-zero targets by 2050, the need for long-duration energy storage (LDES) solutions has transitioned from a future luxury to an immediate utility requirement. Concentrated Solar Power (CSP), alongside large-scale thermal processing applications in heavy industries, depends on a highly stable, high-capacity medium to capture, store, and dispatch thermal energy. Molten salts—primarily eutectic mixtures of potassium nitrate (KNO₃) and sodium nitrate (NaNO₃)—have established themselves as the industry gold standard due to their outstanding heat transfer coefficient, non-toxic properties, and wide operational temperature envelopes.
China remains the global powerhouse for synthetic nitrate production and purification. Chinese chemical manufacturing infrastructure, particularly in industrial corridors like Shanxi, operates at a scale and technological efficiency that is currently unmatched globally. Shanxi Vojin New Materials Co., Ltd. represents this pinnacle of manufacturing competence. Driven since 2000, Vojin has combined mineral abundance, synthetic chemical technology, and international export expertise to service heavy industrial markets, primarily concentrating on solar thermal storage and premium agricultural compounds.
International procurement teams evaluating molten salt suppliers look beyond chemical formulas; they assess supply chain resiliency, purity limits, and price elasticity. Synthetic nitrate manufacturing in China yields highly consistent purity margins compared to natural caliche mining deposits, which can display high concentrations of problematic halides and carbonates. The procurement criteria for Australian renewable projects encompass the following critical vectors:
How high-density molten salt mixtures fuel the thermal, chemical, and agricultural ecosystems across Oceania and global markets.
Capturing Concentrated Solar Power (CSP) and dispatching zero-emission electricity.
View ApplicationUltra-purity chemical baths for glass chemical strengthening processes.
View ApplicationDecarbonizing industrial manufacturing and coal boilers with stored heat.
View ApplicationPremium fully water-soluble fertilizers for high-efficiency drip irrigation.
View ApplicationAustralia’s National Electricity Market (NEM) faces unprecedented volatility as coal plants retire. Large-scale chemical thermal batteries, utilizing molten nitrates, present a stabilizing macroeconomic solution. Unlike lithium-ion battery storage systems that suffer capacity loss over 10-15 years, molten salt thermal storage provides a physical system lifetime surpassing 30 years with virtually zero thermal capacity degradation. By pairing high-purity Chinese-manufactured solar salts with domestic engineering, Australian infrastructure developers can cut capital expenditures (CAPEX) for solar field storage setups by up to 35% compared to European-sourced chemical media.

Our standard binary solar salt consists of a highly controlled mixture of 60% high-purity Sodium Nitrate (NaNO₃) and 40% Potassium Nitrate (KNO₃). This composition exhibits a melting point of approximately 220°C and maintains chemical stability at operating temperatures up to 565°C.
Corrosion is primarily caused by chloride (Cl⁻) and sulfate (SO₄²⁻) impurities in the salt mixture. Our manufacturing processes include multi-stage crystallization systems that reduce total chloride content to less than 100 ppm (0.01%). This significantly lowers the rate of chemical attack on stainless steel materials like 321H or 347H.
Because nitrates are hygroscopic, we package our products in 1.0 to 1.25 metric ton UV-resistant woven polypropylene bags. These are fitted with an inner polyethylene liner (minimum thickness 0.1mm) and heat-sealed immediately after filling to ensure the chemical remains dry from our factory to the project site.
Yes. Beyond standard binary configurations, we formulate ternary mixtures incorporating Calcium Nitrate or Sodium Nitrite to lower crystallization points down to 120°C - 142°C for thermal processes that require a lower melting temperature.
Production and port logistics in China typically take 15 to 25 days, depending on order size. Shipping transits to major Australian ports (such as Fremantle, Adelaide, or Melbourne) range from 18 to 28 days, allowing for a total estimated lead time of 5 to 7 weeks from order placement to port delivery.
