DILATOMETRY PUSH-ROD AND OPTICAL

HIGH-PERFORMANCE DILATOMETERS A dilatometer is a precision instrument for the measurement of dimensional changes in material as a function of temperature. Dilatometry can be used to test a wide range of material including traditional and advanced ceramics, glasses, metals, and polymers. It provides measurements of a wide variety of properties including linear thermal expansion, coefficient of thermal expansion, sintering temperature, shrinkage steps, phase transitions, density change, softening point and decomposition temperature, anisotropic behavior, and glass transition temperature. No single...

DILATOMETRY and the Measurement of DIMENSIONAL CHANGES Understanding DILATOMETRY MEASUREMENT TECHNOLOGIES: PUSH-ROD vs. OPTICAL In a dilatometry experiment, a sample is placed into a holder with one end brought into contact with a push-rod. Alternatively, for a non-contact measurement, the sample is framed by optical CCD sensors. The sample and holder are then enclosed within a furnace where the sample is subjected to a prescribed temperature program of heating, cooling, or isothermal conditions. During the experiment, the linear dimensional change (expansion or contraction) of the sample is...
