Potassium Sulfate (K2SO4) CAS 7778-80-5, High Purity Fertilizer Grade, Industrial Applications

Product Description

Potassium Sulfate (K₂SO₄), also known as Sulfate of Potash (SOP), is a high-purity potassium fertilizer and chemical compound widely used across agriculture, industrial, and manufacturing applications. It is supplied as a white crystalline powder or granules with excellent solubility in water.

Potassium sulfate is highly regarded in agriculture for its ability to provide essential potassium and sulfur to plants without adding chloride (as potassium chloride does). It is often used in fertilizer formulations to improve crop yields, enhance disease resistance, and support overall plant health.

Beyond agriculture, potassium sulfate is used in a wide range of industrial processes, such as the manufacture of detergents, glass, and other potassium-based chemicals.
