Potassium sulfate (K₂SO₄) with CAS number 7778‑80‑5, supplied by Global Optimals, meets a purity of ≥99 % and shows high water solubility of 6.0–8.0 g per 100 ml at 20 °C. The solution remains stable in the pH range of 6.0–8.0, and the compound melts at 840 °C, ensuring reliability during thermal processing. In agriculture, potassium sulfate serves as a potassium fertilizer that enriches soil without the risk of chloride buildup. For storage, keep the material in a dry, cool environment protected from moisture and direct sunlight; polypropylene bags preserve product quality during transport across Uzbekistan, Kazakhstan and Russia.

Potassium sulfate must be stored in a dry, well‑ventilated area, protected from direct sunlight and moisture. Recommended storage temperature is between +5 °C and +25 °C; temperatures outside this range may affect crystal integrity. When packaging remains intact, the typical shelf life is about 24 months. Use protective gloves and safety goggles during handling and avoid inhaling dust. Ensure the sealed polyethylene container shows no damage or leaks.
