Molybdenum Property for Sapphire Growth Furnace

The resource of molybdenum is abundant in the crust is about 1 × 10-6, and it is about 2 × 10-6 in the magmatic rocks of granitoids. In geochemical classification, molybdenum belongs to the transitional pro-iron. Inside Mineral Deposits, combining molybdenum and sulfur can form molybdenite.

Molybdenum is silver-white metal, hard and tough. The density of molybdenum is 10.2 g / cm 3, melting point is 2610 ℃, the boiling point of 5 560 ℃and Valence are 2, 4 and 6, the stable one is 6. Molybdenum is a transition element, and can be easily changed its oxidation state.

Molybdenum plays a role in the redox reaction of passing electrons. In the oxidized form, molybdenum is likely to be in the hexavalent state. During electron transfer, it is also likely to first restore the pentavalent state, but also in the restored enzyme found in the other oxidation state of molybdenum. 

Molybdenum is a xanthine oxidase enzyme / dehydrogenase, aldehyde oxidase and sulfite oxidase components, in order to know these essential trace element for humans, animals and plants. Human various tissues containing molybdenum, the total adult body is 9mg, and molybdenum is higer in liver, kidney content.

Molybdenum products used in sapphire growth furnace are molybdenum wire, molybdenum crucible, molybdenum cover and so on. Besides used in sapphire crystal growth furnace, molybdenum also has other applications. Molybdenum wire can be used in high-temperature furnace and EDM cutting. molybdenum sheets are widely applied in manufacturing radio equipment and X-ray equipment. Multi molybdenum alloy can improve the elastic limit, corrosion resistance, and maintain a permanent magnetic. Molybdenum is required seven micro-nutrients in a plant growth and development, without it, plants can not survive.

Due to molybdenum property of high temperature,heat,etc., molybdenum products are widely used in emerging sapphire growth furnace and other processing industries.


In addition, the combination of molybdenum and silicon make tungsten to be heating element. The following is a mixture of molybdenum and silicon for the heating element.
