COMPETITIVE SOLICIATATION K 4998-3
The National High Magnetic Field Lab (NHMFL) at Florida State University would like
to procure an IR image furnace (also called a Floating Zone furnace). VENDORS ARE
TO SUBMIT COMPLETE DESCRIPTIVE LITERATURE AND SPECIFICATIONS WITH
THEIR BID RESPONSE.
SPECIFICATIONS
- Furnace must include 2 mirror image arrangements
- Temperature range: Furnace must reach at least 2000 degrees Celsius.
- Growth rate: rate of at least 1 mm/hour
- Expected Delivery (approximate): 4 months after receipt of order
- Final payment will be made Net 40 after delivery, testing, and approval by the
researcher.
OTHER UNITS
(1) Furnace must include a cold trap for long-term maintenance.
(2) Transformer: The unit should have the specifications such that we can
accommodate the furnace with our local electrical outlets.
(3) Spare parts: Spare filaments for the halogen lamps.
(4) Hydrostatic press: A press to prepare the polycrystalline rods for crystal growth.

focus radiation upon the polycrystalline rod.
Figure 2: IR Image Furnace at McMaster University. The left side is where the actual
crystal growth takes place, with the controls for monitoring the growth on the right. To
the far left is a hydrostatic press, which is needed for the preparation of the seed rods of
the crystal.

grown with the image furnace at MIT. The scale is mm ruled graph paper.
Figure 4: Actual picture of a crystal growth at McMaster University through a CCD
camera. The molten area of the rod (middle) can be seen, out of which a crystal is being
grown. The blurriness is due to the rotation of the rods, which enhances mixing of the
material and a clean growth.
