Description
Hansol Chemical's industrial grade potassium nitrate is an inorganic salt with the chemical formula KNO₃. It appears as a white crystalline or granular solid, featuring high purity, excellent water solubility, and stable properties, making it a high-quality industrial raw material for multiple sectors.
Key characteristics include:
- High Purity — KNO₃ content typically ≥ 99.0% (higher purity grades such as 99.4% or 99.7% are available upon customer request).
- Excellent Water Solubility — Approximately 316 g/L solubility in water at 20 °C, readily dissolving for easy solution preparation or use in aqueous systems.
- Physical Stability — White crystalline or granular form with uniform morphology, facilitating accurate dosing and packaging.
- Strong Oxidizing Properties — Functions as an oxidizing agent with good chemical reactivity under appropriate conditions; must be stored separately from reducing agents and combustible materials.
