What is Sodium Molybdate?
Sodium molybdate, chemical formula Na2MoO4, is a white rhombic crystal. At 100 ° C, it loses 2 particles of water of crystallization. The melting point is 687 ° C. The mean lethal dose (computer mice, intraperitoneal) 344mg/kg. irritating. Sodium molybdate is soluble in water but insoluble in acetone.
Sodium molybdate can be obtained by oxidizing as well as roasting molybdenum concentrate to generate molybdenum trioxide, leaching with fluid caustic soda to form salt molybdate solution, and after that it can be gotten after suction filtering, concentration, cooling, centrifugation and also drying out. Chemical Security of Sodium Molybdate: Secure under normal storage space as well as handling conditions at area temperature level in closed containers.
Salt molybdate is harmful, yet it is a low poisoning substance. Molybdenum poisoning can trigger joint discomfort, reduced high blood pressure as well as changes in high blood pressure, neurological problems, and disruptions in metabolic processes. The maximum acceptable concentration of soluble molybdenum compound aerosol is 2mg/m, which of dirt is 4mg/m. When calling and also utilizing sodium molybdate, wear the recommended safety equipment. Take notice of moisture. It must be shielded from rain and also sunlight throughout transportation.
Sodium Molybdate Uses
Made use of as a steel deterioration prevention, descaling agent, bleach accelerator, and also skin and hair protectant.
Sodium molybdate (Na2MO4) is utilized as an electrolyte additive for electrochemical capacitors. The addition of Na2MO4 as an electrolyte additive leads to enhanced capacitance, corrosion resistance, and stable performance.
Sodium molybdate is one of the most important molybdates. It is used as a raw material for the manufacture of dyes, molybdenum red pigments, and light-fast color precipitants; it is used for phosphomolybdic acid, sodium phosphomolybdate, molybdate, and molybdenum-containing catalysts , the manufacture of metal corrosion inhibitors and flame retardants for pollution-free industrial cooling water systems; it is also used as analytical reagents for alkaloids, galvanizing, polishing agents, and essential trace components for animals and plants.
Salt molybdate (NazMoO4-2H2O) is an important molybdenum resource that can be applied with other fertilizers or as a foliar spray (39% molybdenum). Sodium molybdate is the sodium salt of molybdic acid. Molybdenum oxide is integrated with sodium carbonate or sodium hydroxide to form sodium molybdate.
Molybdenum is an important element of nitrate reductase, which militarizes the conversion of nitrate (NO 3 -) to nitrite (NO 2 -). It is additionally a part of nitrogenase enzymes involved in nitrogen addiction by rhizobia in leguminous plants. Saturating seeds in a sodium molybdate option (made with mud or dust) before planting is an efficient seed therapy. Salt molybdate is one of the most frequently used molybdenum-containing plant food and can be utilized as a foliar spray or as a garden compost. It is also used in seed treatment.

Application of Sodium Molybdate
Corrosion inhibitor
Cleaning agent
Bleaching delignification
Lubricant
Other applications
Corrosion inhibitor
Sodium molybdate was first used as a corrosion inhibitor in automobile engines. At first, it was used alone. salt, polyacrylate, hydroxybenzoate, phthalate, adipate, benzotriazole, benzotriazole, mercaptobenzotriazole and sodium glucoheptonate.
In ethylene glycol, the concentration of sodium molybdate is usually 0.1% to 0.2%. At this level, the corrosion inhibition of various metals such as steel, aluminum, copper and welding flux in the cooling water system can be maintained. It protects against heat transport corrosion in aluminum cylinder heads, cavitation corrosion in cast aluminum water pumps and pitting corrosion in aluminum radiators. In addition, sodium molybdate has corrosion inhibition effect on low aluminum or high lead solder.
Cleaning agent
A cleaning company in Germany has launched an environmentally friendly meal washing liquid, which is different from other cleaning liquids and contains 300 mg/L sodium molybdate or potassium molybdate.
The cleaning solution formula is 45% sodium citrate, 5% sodium carbonate, 31% sodium bicarbonate, 1% protease and amylase, 2% surfactant, 10% sodium perborate, 4% EDTA, and the rest plus 250 μg / L of sodium molybdate. The dishwashing liquid includes detergent, grease decomposing agent, proteolytic agent, water softener, oxidizing agent, disinfectant and bleaching agent. Among them, 300 μg/L of molybdate had a significant impact on the cleaning effect.
If no sodium molybdate is added, when only the above seven components are contained, the detergency index is only 4, and when a trace amount of sodium molybdate is added, the detergency index for dishes, etc. is 10. However, when adding 124mg/L sodium molybdate or 177 μg/L potassium tungstate, the detergency index dropped to 8.
Bleaching delignification
Chemical pulp made with kraft, traditionally delignified with hydrogen peroxide. It has recently been developed to use a small amount of sodium molybdate to promote the bleaching and delignification of chemical low pulp. This method can be used in ECF and bleaching systems. This method is relatively simple, and the effect of using hydrogen peroxide is better, which can significantly reduce the amount of hydrogen peroxide and speed up the time of bleaching and delignification. In addition, impurities such as iron and manganese in pulp can also be removed from sulfate pulp. This method can be used to produce packaging paper, high-grade paper, etc.
Lubricant
In the preparation of multifunctional lubricant additives, such as molybdenum dialkyldithiophosphate, molybdenum dialkyldithiocarbamate, molybdenum diaryldithiophosphate, molybdenum zinc dialkyldithiophosphate, etc. Sodium molybdate. Dispersing sodium molybdate-alkaline earth metal sulfonate in engine lubricating oil can improve the rust prevention and anti-wear properties of engine lubricating oil. When producing molybdenum diisooctyl dithiophosphate, about 180-220 kg of sodium molybdate is consumed for 1 t of production.
About 1 kg of sodium molybdate is used for every 100 kg of lubricant in the newly developed lubricant for extubation by Japan Steel Tube Company. The white colloid compounded by 1 mol gypsum and 1 mol sodium molybdate is used as a high temperature resistant lubricant for high-grade screws. A surface treatment specially designed for the lubrication of metal sliding parts consists of thiourea, sodium molybdate and a small amount of hydrogen phosphate. In a polymeric solid lubricant specially used for cold-rolled metal materials, the corrosion of the rolling body is obviously prevented due to the introduction of ammonium paramolybdate. Sodium molybdate, sodium borate, bicarbonate, and new graphite lubricants are used in non-flammable and pollution-free thermal calcined lubricants. There is also a new formula of lubricant for drawing metal which is composed of quicklime, soap, citric acid, sodium molybdate and water. This lubricant can not only protect the metal from corrosion, but also has good lubricity.
Other applications
In the electrolyte of Li-MnO2 battery, adding sodium molybdate can protect the stainless steel cathode. Sodium molybdate is also used in the can industry, brake lining production, boiling water, abrasive slurry, oil natural drilling, metal-nonmetal glass and the preparation of various molybdates. In short, the application prospect of sodium molybdate is very broad.
