The new method of complex experimental-theoretic research of TFP of bulk materials is developed with the use of inverse coefficient tasks of heat conductivity for opaque materials and inverse coefficient tasks of radiation-conductive heat exchange for semitransparent materials. On the basis of finite-difference method the numerical methods of decision of the formulated inverse coefficient tasks are developed. On the basis of method of coaxial cylinders the draft design of the experimental setting is developed allowing to conduct researches of experimental standards to the temperatures 1500 °C in the automatic mode. On the base of method of coaxial cylinders the draft design of the experimental setting, allowing to conduct researches of experimental standards in the interval of temperatures to 1500 C is developed in the automatic mode. System of automatic control the temperature conditions of setting and capture of data software is developed on a temperature, strength of current and tension in the working cell of setting and processing of experimental data, including the decision of inverse coefficient tasks. A new experimental fluidizer is created implementation of the high temperature measurings of TFP of friable materials, allowing to execute researches of heat conductivity with the expected systematic error at a confidence interval 0,68 no more than 12 %. Approbation of the developed method of research of TFP is conducted on standard and friable materials - heat-insulation charge of different particle-size and friable barrier mixture in the interval of temperatures to 1200 °C and the certification of the developed setting is executed.
