METHOD TO DETERMINE HEAT CONDUCTIVITY AND TEMPERATURE CONDUCTIVITY OF MATERIALS Russian patent published in 2015 - IPC G01N25/18 

Abstract RU 2548408 C1

FIELD: measurement equipment.

SUBSTANCE: in accordance with the proposed method they record electric signals corresponding to initial temperatures of surfaces of the investigated sample of the material of at least two reference samples with available heat conductivity and temperature conductivity. Surfaces of investigated and reference samples are heated by an optical source of heat, and electric signals are recorded, which correspond to temperatures of heated surfaces of investigated and reference samples along the heating line, and also in parallel to the heating line at the distance from it. Heat conductivity and temperature conductivity of the investigated sample is determined on the basis of difference of output electric signals corresponding to heated and non-heated surfaces of investigated and reference samples.

EFFECT: increased accuracy of determination of heat conductivity, temperature conductivity and volume heat capacity of materials without preliminary processing of material surface for balancing of their optical characteristics.
