[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods, chemical properties of sodium molybdate

SODIUM MOLYBDATE PROPERTIES

Sodium molybdate (sodium Molybdate) is the sodium salt of molybdenum with the chemical formula Na₂ MoO₂. It usually exists in the form of anhydrate or dihydrate. Sodium molybdate is white or colorless crystalline powder, soluble in water, insoluble in alcohol. The solution is weakly alkaline and has good stability. The melting point is around 687°C and the density is 3.28g/cm³. Sodium molybdate has strong oxidation resistance and corrosion resistance, which makes it widely used in many fields.

Sodium molybdate uses

Sodium molybdate is widely used in industry and agriculture. In agriculture, sodium molybdate is an important trace element fertilizer, which can promote the absorption of nitrogen by plants and improve the yield and quality of crops. In industry, sodium molybdate is used as a raw material for metal molybdenum, which is used in the manufacture of alloys, catalysts, pigments and electronic materials. It is also an effective preservative and corrosion inhibitor, widely used in water treatment, metal processing and coating industries. Sodium molybdate is also used in the pharmaceutical industry, as a pharmaceutical ingredient or reagent, with anti-inflammatory, anti-cancer and other pharmacological effects.

Upstream raw materials

The production of sodium molybdate mainly depends on molybdenum ore and sodium carbonate or sodium hydroxide. Molybdenum ores mainly include minerals such as molybdenite (MoS₂), which are converted into sodium molybdate by high temperature oxidation or roasting. In the production process, molybdenum ore first needs to be crushed and concentrated, then reacts with oxygen in the air under high temperature conditions to produce molybdate, and finally reacts with sodium carbonate or sodium hydroxide to produce sodium molybdate. By-products of the production process, such as sulfur dioxide and other waste gases, need to be treated to reduce environmental pollution.

Downstream Products

Sodium molybdate is an important chemical intermediate, and its downstream products involve many fields. Sodium molybdate is an important raw material for the production of molybdenum metal and its alloys, which are widely used in aerospace, military and electronic industries. Sodium molybdate is a key component in the production of catalysts, especially in petrochemical and environmental protection catalysts. Sodium molybdate is widely used in water treatment agents and metal surface treatment agents, which can effectively prevent metal corrosion and improve metal surface quality. In the agricultural sector, sodium molybdate is used as a micronutrient fertilizer, significantly increasing the growth and yield of crops.

SODIUM MOLYBDATE STORAGE METHOD

Sodium molybdate should be stored in a dry, ventilated and cool place to avoid moisture and high temperature environment to prevent its decomposition and deterioration. Storage containers should be well sealed to avoid contact with acids to prevent chemical reactions. Because sodium molybdate has certain toxicity, it should be protected during storage and use to avoid inhalation of dust or contact with skin. The storage conditions should be checked regularly to ensure that the container is intact to prevent leakage of sodium molybdate and pollution of the environment.

Sodium Molybdate Market Prospects

With the advancement of industrialization and the increase in agricultural demand, the market demand for sodium molybdate has gradually increased. Especially in the field of environmental protection and new energy, sodium molybdate, as an important component of catalyst and preservative, has steadily increased its demand. The increasing demand for high-performance alloy materials worldwide has driven the application and market expansion of sodium molybdate. It is expected that in the next few years, the sodium molybdate market will maintain steady growth and become an important part of the chemical industry.

Production technology and environmental impact

The production technology of sodium molybdate has been continuously developed to improve production efficiency and reduce environmental impact. Modern production technologies include efficient purification and green chemical synthesis processes that reduce energy consumption and waste emissions. The waste gas, waste water and solid waste generated in the production process of sodium molybdate need to be effectively treated and recycled to reduce the negative impact on the environment. The promotion of sustainable development and environmental protection policies will further promote the development of sodium molybdate production technology in a green and low-carbon direction.

Summary

As an important chemical product, sodium molybdate has a wide range of uses and good market prospects. Its excellent physical and chemical properties make it play an important role in agriculture, industry and medicine. Although there are environmental challenges in the production process, with the technological progress and the strengthening of environmental protection measures, the production and application of sodium molybdate will be more environmentally friendly and efficient. In the future, sodium molybdate will continue to play its unique role in various fields and become an important force in promoting economic and technological development.
