Molybdenum Crucible Resistance Furnace

Molybdenum crucibles used in resistance furnaces can extend the service life. The advantages of the molybdenum crucible resistance furnace are good temperature controllability and the rigidity of the molybdenum crucible at high temperatures. Molybdenum crucibles are sintered and forged from the final material. Generally, molybdenum crucibles are made of pure molybdenum, which prevents the molten metal powder from mixing. The density of the molybdenum crucible is greater than 9.8g/cm3, and its working temperature is between 1100℃. Besides tungsten crucibles in the metal melting industry, it is another good choice.

Molybdenum crucibles are widely used in the metallurgical industry, rare earth industry, artificial crystal, and machinery. Since the melting point of molybdenum is as high as 2610°C。 The working temperature environment of the molybdenum crucible is generally above 2000℃. Especially for the sapphire single crystal growth furnace, the molybdenum crucible with high purity, high density, no internal cracks, accurate size, and smooth inner and outer walls can be used for the success rate of seeding, crystal pulling quality control, recrystallizing and sticking in the process of sapphire crystal growth.

The Molybdenum Crucible Dual Vacuum Furnace contains an inexpensive removable Molybdenum liner that extends the life of the crucible.

The shutter shaft is fitted with a 1-inch movable linear drive.

1.33-inch flange with a flexible line to connect to the vacuum system.

1.33-inch flange equipped with 0.75-inch length zero viewport funnel assembly for visual inspection.

VAT special series 48 gate valve with all metal sapphire window welded into the valve. The visual effect for heating the crucible floor on the sample.

The shutter is equipped with a cup to capture any stray sample particles with a 0.25 diameter vacuum mirror. A mirror mount, through a zero-length viewport (4), provides browsing access at the bottom of the sample heating crucible.

The rotary drive is driven by a DC stepper motor.

1.33" opposite flange drawing. Provides access to the non-analytical "Roughing" section.

Linear drives drive DC stepper motors.
