A crystal growth tube furnace incorporating a programmable motion system to “rock” the complete hot zone for long durations while maintaining temperatures up to 1300°C in an oxidizing environment.

The heated zone consists of a 50″ long mullite tube with resistance type heating elements. The hot zone contains three independent heating elements.

The complete hot zone is able to continuously rock at 90° angles and is provided for growing crystal composites.

Once the rocking heat cycle is complete, a unique quenching system will drop the crystal composites to a controlled depth in a cooling medium for quick cooling.
