Description

Sylvinite CAS NO 77348-01-7 is a naturally occurring mineral mixture, primarily composed of sylvite (potassium chloride, KCl) and halite (sodium chloride, NaCl). This composition makes it a critical raw material for the production of potash fertilizers, which are essential for global agriculture and food security. It is a fundamental resource for the fertilizer industry, mining sector, and chemical manufacturing, where potassium is a key nutrient and industrial chemical precursor.

Application

• Potash Fertilizer Production: The primary and most significant application is as the main ore for the manufacture of muriate of potash (MOP) and other potassium-based fertilizers.
• Chemical Manufacturing: Serves as a source material for producing various potassium chemicals, including potassium hydroxide and potassium carbonate.
• De-icing Agents: Processed material can be used in formulations for road de-icing, offering an alternative to pure sodium chloride.
• Water Softening Salts: Can be utilized in certain industrial water softening processes where potassium chloride is preferred.
• Animal Feed Supplement: Refined potassium chloride from sylvinite is used as a nutritional supplement in livestock feed.
• Industrial Brines: Used in the creation of specialized brines for oil and gas drilling operations and other industrial processes.

Quality Control

Our Sylvinite is sourced and processed under strict quality protocols to ensure consistent composition and performance for industrial applications. Quality is assessed based on key parameters such as potassium oxide (K₂O) equivalent content, NaCl:KCl ratio, and impurity levels. Certificates of Analysis (COA) detailing the specific grade's composition are available upon request to meet your procurement and production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the material must be kept in a low-humidity environment to prevent caking and moisture absorption. Isolate from incompatible materials.
