The vertical dilatometer is an accessory to the Laser Flash Thermal Diffusivity system. This dilatometer can be used to measure thermal expansion of such high temperature materials as carbon-carbon composites. Linear thermal expansion can be measured from RT up to 2400^oC. Bi-layer differential expansion of due to bending is measured from RT up to 1450^oC.

Features:

• Linear thermal expansion measurements from 20 to 2400^oC
• Measurements in inert gas or vacuum environments
• Dedicated computer control of time-temperature programs for the samples
• Length-change data automatically acquired, analyzed, and plotted

Applications:

In addition to measuring the coefficient of thermal expansion (CTE) as a function of temperature, the dilatometer can serve as a probe to detect various physical or chemical changes in a specimen. For example, the occurrence of a phase change or the approach to the Curie point of a material is almost always accompanied by a change in thermal expansion. The dilatometer can also be used to follow the course of a sintering process.
