The Magic metal—Molybdenum（3）

Molybdenum is a kind of rare metal, also，it is one of the important strategic non-renewable resources and the basic material of development of high and new technology, national modernization and the construction of modern defense. With the continuous development of science and technology, molybdenum is widely used in steel industry, non-ferrous metal industry, nuclear industry, aerospace industry, chemical industry, electronic industry and other fields because of its unique performance. At the same time, various emerging applications of molybdenum were constantly found which made this magical molybdenum metal more colorful.

The role of molybdenum played in human body

Molybdenum is one of the important trace elements in organisms, which is the constituent part in three kinds of metallothionein of mammals. In the biological oxidation reaction，the molybdenum transformed between pentavalent molybdenum and hexavalent molybdenum, it plays the role of electron transfer, which has a close relationship with the biological cells in the body and the breathing and metabolism of nucleoprotein.

Molybdenum involved in the metabolism of the carbohydrate, fat and vitamin in the human body, and it is part of various enzymes which can promote one’s grow-up and prevent anemia or dental caries; the combination of molybdenum and fluorine can increase the density of bones and the content of calcium and magnesium which prevent kidney stones and kaschin-beck disease; molybdenum can block the synthesis of carcinogenic nitrosamines in the human body, thus inhibiting the occurrence of cancer of the stomach; molybdenum protects normal cells genetic factor from carcinogens interference; molybdenum can reduce the absorption of carcinogens in the body and accelerate the excretion.

The application of Molybdenum in the field of medicine

The medical titanium molybdenum alloy with microporous structure has good biocompatibility and mechanical properties, and it can be matched well with the elastic modulus of human hard tissue, thus it is a good material of hard tissue repairement and replacement.

In X-ray line inspection, the tungsten target X-ray line relatively has short wavelengths and strong penetrating power that is suitable for deep and dense tissue. Meanwhile, molybdenum target X-ray has a longer line of wavelength and a weaker penetration that mostly absorbed by soft tissue, which can make it clear that human body tissue within the structure and small lesions are like. Molybdenum target X-ray inspection has become one of the most effective and reliable means of the diagnosis of breast lesions.
