Sodium Molybdate – High Purity Molybdenum

Sodium Molybdate (Na₂MoO₄·2H₂O) is an inorganic molybdenum compound that appears as a white crystalline powder or granule. It is highly valued for its role as a molybdenum micronutrient and its effectiveness in corrosion-resistant formulations and metal surface treatments.

In agriculture, it is used as a trace element fertilizer for leguminous crops to enhance nitrogen fixation and plant growth. Industrial applications include its use as an oxidation catalyst, metal corrosion inhibitor, ceramic additive, and metal finishing agent.

MDNR Resource supplies high-purity Sodium Molybdate (≥99.5%), meeting global standards for use in agriculture, water treatment, and chemical processing industries. We ensure consistent quality, bulk availability, and prompt delivery worldwide.

Extraction from Molybdenite Ores

1. Molybdenum disulfide (MoS₂) is roasted to produce molybdenum trioxide (MoO₃).

2. MoO₃ is then dissolved in sodium hydroxide, forming sodium molybdate crystals.

3. Final product is filtered, crystallized, and dried to meet industrial-grade standards.

1. Is Sodium Molybdate suitable for foliar application?

Answer: Yes, it can be applied directly to leaves in diluted foliar sprays for targeted nutrient uptake in crops.

2. What is the recommended dosage for agricultural use?

Answer: For soil application: 100–150g/acre. For foliar spray: 0.5–1g/L of water, depending on crop type and soil condition.

3. Can it be used in drinking water systems?

Answer: It is typically used in industrial water treatment systems, not potable water. Use in drinking systems requires strict compliance and safety evaluation.

4. How do you ensure consistent quality and compliance?

Answer: MDNR Resource sources material from ISO-certified plants, tests every batch in accredited labs, and complies with REACH and agricultural regulatory standards.
