Abstract

Properties of functional materials on the base of melted high purity lanthanum chromite of composition La_0,975Ca_0,025CrO₃ with addition of Y₂O₃ is described. Functions relation of the normal integral radiant emittance and relative density via content of Y₂O₃, electrical conductivity of the material via temperature are shown. Example of using of the functional material for heater elements is presented. High value of specific surface power and effective radiant emittance allow using of the material as models of blackbody.
