With
the Tri-arc unit we are capable of Czochralski-type growth methods
which are not possible with the optical floating zone units. This
unit melts conductive materials with an arc temperature of up to
~3000 degrees C. The unit is used for arc melt/synthesis of feed-rod
materials for the OFZ units. Crystal growth can be conducted under
vacuum or inert atmosphere conditions with either a graphite or
water-cooled copper hearth.
