Dilatometry
  Description
The UNITHERM™ 1091 multi-sample dilatometer
is a fully computerized dilatometer system designed to measure
dimensional changes of a specimen brought about by changes
in its thermal environment.
Properties Measured
The dilatometer can determine linear thermal
expansion coefficient (CTE),
annealing characteristics, and other physical or chemical
changes manifesting themselves in a change of linear dimension.
Studies of processing parameters as reflected by dimensional
changes of the material can be studied in great detail through
duplication of thermal cycles and rates used in the actual
process. Due to the flexible programming of thermal cycles,
complex processes can be easily simulated.
