METHOD OF SIMULTANEOUS DETERMINATION OF MATERIAL HEAT CAPACITY AND THERMAL EXPANSION Russian patent published in 2012 - IPC G01K17/00 G01N25/20 

FIELD: physics.

SUBSTANCE: calorimetre cell made up of at least two concentric thin-wall tubular cases is fitted into dilatometric system to determine heat capacity. Analysis is carried out in vacuum on rod-shaped specimens characteristic of dilatometric analysis. Material heat capacity is defined from the results of two calibration and one main experiments conducted on heating calorimetric cell inner case at the rate constant for all experiments. Experiments over, first calibration experiment is subtracted from total data differences to determine temperature differences of cases corresponding to heating of solely standard and analysed specimens to be used for determination of heat capacity of analysed specimen from enclosed formula.

EFFECT: possibility of simultaneous determination, higher accuracy of determination.
