Description

Sodium Molybdate Dihydrate is an essential inorganic salt that serves as a vital source of molybdenum, a crucial trace element. This high-purity compound is valued for its consistent quality and reliable performance in demanding industrial and technical processes. It is a key material for manufacturers in the water treatment, corrosion inhibition, catalyst production, and agricultural micronutrient sectors seeking a stable and bioavailable molybdenum source.

Application

• Corrosion Inhibitor: A critical component in closed-loop cooling water systems and automotive antifreeze/coolant formulations to protect ferrous metals (steel, cast iron) from pitting corrosion.
• Water Treatment: Used as an anodic corrosion inhibitor in industrial water treatment programs for boilers, heat exchangers, and recirculating systems.
• Catalyst & Chemical Synthesis: Acts as a precursor or catalyst in various chemical reactions, including oxidation processes and the production of pigments and other molybdenum compounds.
• Agriculture & Animal Feed: Provides a soluble and bioavailable source of molybdenum, an essential micronutrient for plant growth (in fertilizers) and animal health (in feed supplements).
• Metal Finishing & Plating: Employed in electroplating baths and surface treatment solutions for coating metals and alloys.
• Laboratory & Analytical Reagent: Serves as a standard or reagent in analytical chemistry and research laboratories.
• Ceramics & Pigments: Used in the manufacture of ceramics, glasses, and inorganic pigments to impart specific properties or colors.
• Flame Retardant & Smoke Suppressant: Finds application as an additive in certain polymer and material formulations to improve fire resistance.

Quality Control

Our Sodium Molybdate Dihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, heavy metal content, and other critical parameters. A Certificate of Analysis (COA) is provided with every shipment, detailing the results of these quality control tests to guarantee consistency and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and caking.
