Method for measuring properties of thermoelectric materials and the measuring probe for this method

摘要

the subject of the invention is the measurement method of electron namely.seebecka coefficient and electrical conductivity of the test material, which scan the surface of test samples using "hot probe", about the new design.equipped with a temperature sensor blades and adjustable mikrogrzejnik. the homogeneity properties of valves by measuring local thermoelectric parameters namely.seebecka coefficient and electrical conductivity, characterized by that it is a temperature measurement probe measuring blade, under the conditions laid down,before you touch by measuring probe surface of the test sample material and simultaneously measure temperature reference electrodes.a constant voltage of seebecka u0 in time (t = 0), and a variable voltage component seebecka ualt in time (t = 0).local absolute coefficient seebecka material test sample shall be calculated according to the relationship am = am u0 / (t2 - t1) -? s, where as is the seebecka materialused for the probe, the probe is temperature (t2) at the time t0, and the temperature (t1) reference electrodes in time t0, while the local resistance r is calculated according to the relation r = ualt / l,where l is the effective of the alternating current flowing through the test sample.the subject of the invention is the probe measurementin the form of a solid body made of hard material with a low absolute coefficient and high thermal conductivity and electric seebecka, favourably with precious metal alloys, for example.ptrh, irrh, carbide elements block d (tic, wc,...), in the shape of inverted cone simple o h? 2r.
