Muriate of Potash
Muriate of Potash MOP Exporter, Manufacturer
Muriate of Potash MOP is a high purity, dry crystalline inorganic/metal halide salt composed of potassium and chlolrine, KCl. It has a molar mass of 74.551 g/mol and occurs naturally as the mineral slyvite. Muriate of Potash MOP is often referred to as muriate of potash (MOP), particularly when used as a fertilizer.
• Primarily used as a shale inhibitor as the potassium ion exchanges with calcium and sodium ions n the interlayer space in illites and smectites, converting them to more stable mica-type structures that do not hydrate and swell.
• Used to prepare brines for drill-in, completion, and workover fluids
