60 kinds of plant organisms from the elements, nitrogen, phosphine, potassium fertilizer plant three factors. Few content elements boron, manganese, zinc, copper, cobalt, molybdenum, iodine is called seven micronutrient elements and began to receive attention, has been used in the United States, Japan and other more than 20 countries, China in the late 1950s began to apply and now includes more than a dozen trace fertilizer varieties already included in the production of molybdenum applications. 

 

American Association recommends fertilizer oversight, 1t per average common fertilizer should be added boron 0.2kg, 0.5kg zinc, 0.5kg manganese, 0.5kg copper, 1kg iron, 0.005kg molybdenum. Township of South China, Hunan Changsha County with Ammonium dressing, peanut yield 32.2% Tokusho County, Guangdong rice filling stage spraying molybdenum in fertilizer, rice yield of 25.6%, Heilongjiang State Farm since 1957 molybdenum application on soybean trials, the development of large-scale aerial spraying and seed dressing, resulting in soybean yield of about 10%. 

 

Molybdenum and molybdenum compounds for other purposes is still widespread. There are also other uses such as: Black molybdenum films for solar energy conversion dark mirror. For efficient photothermal conversion of solar energy, the need for a high solar absorptance and a high infrared reflectivity match, and a molybdenum film is preferably a black material. 

    

Flame retardants and smoke suppressants organic polymer; British study showed that 3% to 4% of molybdenum trioxide in a halogenated polyester, and make critical oxygen index (minimum burning organic matter O / N) increased 3 % to 4%, the amount of carbon when burned to generate an increase of about 4%, 3% reduction in the amount of smoke so. 

    

Water corrosion: molybdenum heteropoly salt water can be used as a corrosion inhibitor, at 50 ℃, pH8.13 ~ 8.25 environment, molybdenum steel sheet did not add salt before corrosion rate 1.241mm / a, plus molybdenum after heteropoly salt corrosion rate dropped to 0.15mm / a or less. Especially phosphorus, sodium molybdate better, more corrosion rate of 95%, which is particularly important for vessels operating in seawater. 

    

137Cs recovered composite ion exchange material, ammonium phosphomolybdate (AMP) ion exchange material may be applied to the recovery 135Cs, 137Cs its selectivity and high corrosion resistance, the ion exchange material, compared with the other, exchange capacity and rinsed are superior.
