Single Crystal Growth Furnace
NiMnGa crystals are artificial and need to be grown in specific conditions. In addition, the only current demand for NiMnGa crystals is for research purposes. Consequently, purchasing a NiMnGa crystal is very expensive. Therefore, we grow our own crystals with this furnace. Like many of our machines, we are proud to say that the furnace was constructed by one of our students, Doug Kellis. Since his graduation, other students have made improvements and we are constantly increasing the furnace’s usefulness.
This tube furnace is used to anneal and heat-treat the crystals. In the furnace, we can pull a vaccuum and flush the oxygen out with argon. The pressure in the Annealing Furnace can be set within the range: 4.3E-4 to 1200 mbar. The maximum temperature is 1100 C.
The Reitel Furnace is an induction heated casting machine. We use this furnace in conjunction with the vacuum by lowering a quartz tube into the furnace having pulling a vacuum in the quartz tube. We can also flush argon through the chamber and set a desired pressure.
