Description

Carnallite CAS NO 1318-27-0 is a naturally occurring evaporite mineral and a significant source of both potassium and magnesium. Its primary commercial value lies in its role as a key raw material for the production of potash fertilizers and magnesium compounds. This makes it an essential industrial chemical for the agricultural and chemical manufacturing sectors. Reliable sourcing of high-purity carnallite is critical for ensuring consistent product quality in downstream processes.

Application

• Primary raw material for the production of potash (potassium chloride) fertilizers.
• Source material for the extraction and production of magnesium metal and magnesium oxide.
• Used in the manufacture of specialty magnesium salts and compounds.
• Key feedstock in the chemical industry for producing various potassium-based chemicals.
• Component in certain types of construction materials and cements.
• Used in water treatment processes as a source of magnesium ions.
• Applied in laboratory and research settings as a chemical reagent.

Quality Control

Our Carnallite is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and purity. We provide comprehensive Certificates of Analysis (COA) for all shipments, detailing key parameters such as potassium (K2O) content, magnesium (MgO) content, chloride levels, and moisture. Our quality assurance system is designed to meet the rigorous demands of the fertilizer and industrial chemical markets.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and degradation. Recommended storage temperature is between 15°C and 25°C. Keep away from incompatible materials.
