METHOD OF HEAT CAPACITY MEASURING UNDER QUASI-ADIABATIC CONDITIONS Russian patent published in 2018 - IPC G01N25/20 

FIELD: measurement technology.

SUBSTANCE: invention relates to the field of materials research or analysis by means of thermal facilities using the calorimetric measurements by measuring of the heat capacity or thermal conductivity. Materials heat capacity measuring method according to the adiabatic calorimeter scheme consists in the fact, that selection of the starting point for determining the sample heating temperature in the calorimeter with periodic fluctuations in the sample temperature is done in such a way that the temperature change rate at a given time interval was minimal, and the temperature measurement point was preceded by a segment of sample temperature growth. This method can be performed in the form of a series of measurements. At that, the proposed method does not limit possible modes of measurement, i.e. measurements can be carried out both with heating and with cooling with different steps in temperature.

EFFECT: reduction in the time spent on research, as well as reducing the measurement error.
