 In
the Single Crystal Growth Laboratory, there are several different
furnaces available for use. The furnaces are used for sintering,
preparing powders for crystal growth, developing charges prior to
growth, and drying. The laboratory has a range of ovens, box furnaces
and tube furnaces that span the range from a few hundred degrees
C up to 1800 degrees C.
The small ovens are suitable
for low temperature (< 1000 degrees C) heating in air. A MoSi2 heating
element box furnace allows operation in air up to 1750 degrees C.
Four tube furnaces allow controlled atmosphere operation (inert,
oxidizing or reducing atmospheres). There are two 1200 degree C,
one 1500 degree C and one 1800 degree C tube furnaces. The 1200
and 1500 degree C furnaces are three-zone type with independent
control of each zone.
