FIELD: analysis of powder samples.
SUBSTANCE: composition of two-component powder samples with different conductivities is determined by means of electric aids and it can be used for checking composition of powder charges when producing different heating elements as well as for determining electro-conducting impurities in non-conductive powders. The same load is applied to powder sample at any measurement of electric conductivity and percent composition of components of powder sample is determined by means of calibration curve showing dependence of powder mixtures on their composition.
EFFECT: improved precision of measurement.
