Molybdenum crucible has been widely used in rare earth metallurgy, vacuum sintering, laser crystal growth and other industries, which makes the use of the crucible have become the concern of the majority of manufacturers.
 
Molybdenum crucible is divided into: sintering, stamping, machining, and welding molding. In a variety of molding products, the stamping mold crucible is most widely used, and the price is cheap.
 
The price of molybdenum crucible is low, the use of time is greatly lengthened, which has been the first choice for procurement.
 
However, in the process of use, a lot of manufacturers reflected that they previously set up a factory production of the crucible, there are some problems to have to repair. In fact, it is only the method used in the welding of molybdenum crucible, and the choice of the welding environment and the material that is not well, and there is no suitable heat treatment after forming so as to the crucible is not durable.
 
Tungsten rods, molybdenum rods are handled well in these steps, the use of temperature and the length of time of the same thickness of the welded molybdenum crucible and sintered molybdenum crucible is the same, and some even far higher than the use of the sintering crucible.
