Potassium Chloride (Crystal)

High-purity Potassium Chloride crystals with purity exceeding 99.0%, primarily used as a shale inhibitor in oilfield operations. K+ ions enter between clay crystal layers to prevent hydration and swelling, maintaining borehole stability. In laboratories, it is used to prepare standard conductivity solutions, buffers, and various aqueous media. Its precise crystalline form and low impurity levels ensure stable chemical properties after solution preparation, serving as a basic raw material for drilling fluid and water treatment research.
