Molybdenum is an indispensable trace element for crop growth.In the soil lacking molybdenum,adding some molybdenum fertilizer appropriately can increase the nitrogen fixation ability of crops,make crops grow better and increase the yield.More and more data prove that molybdenum is also an essential trace element for human body.The amount of molybdenum in the human body is very small,accounting for only one part per million of body weight.
At present,tungsten crucible is widely used in quartz glass melting furnace,rare earth smelting furnace and other industrial furnaces,and its working temperature environment is generally above 1900℃.Especially for sapphire single crystal tungsten crucible,it has the characteristics of high purity,high density,no internal crack and precise size.The tungsten crucible plays a key role in the quality control of the seed success rate of sapphire crystal growth and the use of the decrystallization cauldron.
Molybdenum crucible according to the manufacturing method can be divided into different type sintering,stamping and welding forming several major production processes,such as stamping crucible in the molybdenum crucible product used in the current market,also widely application and relatively inexpensive means,but affected by the processing technology of it has an inherent difficult to improve the weakness is the thickness of thin,is not conducive to use for a long time on the reuse of the number of poor performance.
Tungsten crucible is widely used in all kinds of forming products,because the tungsten crucible will be affected by the processing technology when it is used,and the thickness is relatively thin.If it is not used properly,the service life will be affected.
