Sodium nitrate: "Molten Salt Grade pursues ultimate purity, Industrial Grade delivers cost-effective performance."
description1
Key Product Properties of NaNO₃ (Nitratine):
✓ Crystalline Composition: Colorless transparent trigonal crystal system
✓ Stability Profile: Maintains integrity at ambient temperatures (humidity-controlled storage recommended)
✓ Thermal Behavior: Decomposition initiates at 380°C (critical for molten salt applications)
✓ Solubility Performance:
● High aqueous solubility
● Liquid ammonia miscibility
● Endothermic dissolution mechanism enabling solution cooling)
✓ Solution Characteristics: pH-neutral aqueous medium
Technical Advantages:
● Molten Salt Optimization: Our molten salt-grade NaNO₃ meets stringent requirements for thermal storage systems and high-temperature industrial processes
● Phase Transition Expertise: Controlled crystalline transitions ensure product consistency across temperature gradients
● Environmental Synergy: Closed-loop NO₃⁻ recovery converts 98%+ of NOₓ emissions into marketable Nitratine
Applications of Molten Salt-Grade Sodium Nitrate
1. Metallurgical Heat Treatment
● Primary use in quenching salt baths as a molten salt medium for controlled cooling of metals (e.g., aluminum, steel alloys).
● Maintains stable thermal conductivity at high temperatures (up to 600°C).
2. Solar Energy Storage
● Key component in concentrated solar power (CSP) systems for high-temperature thermal energy storage (often blended with potassium nitrate).
3. High-Temperature Industrial Processes
● Heat transfer fluid in chemical reactors requiring precise temperature control.
● Oxidation-resistant medium for glass tempering furnaces.
Applications of Industrial-Grade Sodium Nitrate
1. Glass Manufacturing
