Molybdenum has the highest melting point of all metals as well as a remarkably high modulus of elasticity. Molybdenum is still easy to machine. So, molybdenum and their alloy is the best choice for the all kinds of high temperature furnace. They can easily withstand even the most intense heat.
So incorrect Ramp levels can definitely cause crucible cracking. The second reason is much easier - the user shuts the power supply off or has a very short ramp down time for power after the deposition is done. This causes the rapid solidification of the melt, and this stresses out the crucible liner.

A 5-horsepower vacuum pump with a capacity of 110 cubic feet per minute produces an ultimate furnace vacuum of 15 microns with a leak rate of less than 3 microns per minute. This pump is more than ample for the system. Melting Furnace Operation. The melting and casting operation begins with the selection and fabrication of an electrode.
most popular high temperature crucible furnace. Home; Vacuum furnace equipment; Top 10 Ways to Maximize Crucible Service Life | Foundry . In a fuel-fired furnace, operating the burner with excess air and direct flame impingement on the crucible surface will produce damaging oxidation of the crucible.
Our pressed-sintered crucibles made of tungsten have a surface roughness of less than 0.8 µm. The sapphire can be extracted from the crucible without difficulty and without damaging the surface of the crucible. For the sapphire producers, this results in less complex and expensive reworking of the surface of the crucible.

Molybdenum crucible is sintered or forged from the ultimate material—molybdenum powder. Generally speaking, molybdenum crucible is used pure molybdenum, for its purity can prevent melting metal powder from mingling. The density of molybdenum crucible is more than 9.8g/cm3, and its working temperature is among 1100℃.
How to debinding in a sintering vacuum furnace for Metal injection molding. First why we need debinding in a sintering vacuum furnace? After debinding machine there are still 2-3wt% high temperature binder in the products to keep it's shape.so the first step of sintering furnace it to remove these rest binder(<600 degree).
Tungsten crucible is widely used in sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other core containers of industrial furnace. Its operating temperature environment is more than 2000 degrees. Tungsten crucible is widely applied in vacuum sintering, laser crystal growth and other industries.
