Our Arc Melt Furnace with the Crystal Growth option has a larger chamber, larger power supply, top loading instead of bottom loading for easier access, and larger melts. The crystal growth components are set up to grow single crystals of semiconductor materials, metals, salts and synthetic gemstones using the Czochralski method.
This furnace has three electric stingers, for simultaneously melting material with three arcs in three different places. This furnace is capable of melting materials above 3500°C. A crystal seed attached to the seed rod then lowers into the center crucible of the 9″ (225 mm) hearth holding the melt and is programmed to pull the growing crystal.
The pulling speed is fully programmable and controls accurately as low as 0.001 mm/min. The 3/8” seed rod has an adjustable rotational speed from 0-30 rpm. The maximum pull height is 7″ (176 mm).
Key Features of the Arc Melt Furnace (with Crystal Growth Option):
l Equipment Structure and Operational Optimization
Ø Equipped with a larger chamber and a higher-power power supply
Ø Adopts top-loading design (instead of bottom-loading) for easier access and operation
Ø Capable of handling larger-scale melts
l Crystal Growth Capabilities
Ø Supports single crystal growth of various materials (semiconductor materials, metals, salts, and synthetic gemstones) using the Czochralski method
Ø Crystal growth parameters are fully programmable, with a pulling speed as low as 0.001 mm/min
Ø Equipped with a 3/8-inch seed rod, featuring adjustable rotational speed (0-30 rpm) and a maximum pull height of 7 inches (176 mm)
l Melting Capacity
Ø Built with three electric stingers, enabling simultaneous melting of materials at three different positions
Ø Can melt materials at temperatures exceeding 3500°C
Ø Uses a 9-inch (225 mm) hearth, with a central crucible for holding the melt and facilitating crystal growth with the seed
Crystal Puller Components | · A servo motor and drive for controlling the travel speed · A gear reducer to allow slow pulling speeds from 14 mm per minute down to 0.001 mm per minute · A precision slide to move the seed rod up and down in the chamber, 7” (178 mm) of travel · A DC motor to allow the seed rod to be rotated 0 to 30 RPM · Vacuum tight seal around seed rod to isolate the chamber environment · Touch screen to provide easy programmable operation and display of the crystal puller · Control Enclosure houses all electrical components · Slide, motors, gearboxes and seed rod attach to a support rod aside the furnace frame |
Performance | The puller travel speed ranges from 0.001 mm per minute to 14 mm per minute depending on servo motor speed. Seed rod rotation of 30 RPM maximum. |
Operation | In order to grow a crystal the melting of the sample must be used in conjunction with the crystal puller. When growing crystals, a customer-supplied seed crystal has to be attached to the seed rod. This seed is then lowered into the melt, and is slowly pulled up with the provided crystal puller in order to grow a larger crystal. The maximum travel distance is approximately 175 mm (7”). The arc melting furnace is used to melt the raw material in the crucible with the three arcs. Once melted, the stingers can remain in place to keep a homogeneous melt for growing the crystal. |
General Specifications | l for crystal growth using Czochralski method l adjustable pulling speed as low as 0.001mm/min. l 7″ (178 mm) travel l 2″ (50mm) crucible l adjustable seed rod rotation l Tri-Arc melting furnace for fast homogeneous melts up to 3500°C |
Application:
Ø Crystal growth
Ø Arc casting
Ø Powder melting
Ø Annealing
Ø Melting point determination
Ø Production of metallic buttons
Ø Creation of alloys
Ø Crucible welding
Ø Material densification
Ø Preparation of high purity melts
