the Method of low-temperature adsorption of nitrogen

Values of the area of specific surface and the porosity investigated in work rutenijsoderzhashchih of composites and initial samples of Union of Right Forces were defined by a method of low-temperature adsorption of nitrogen by means of the device of a pre-treatment of samples Beckman Coulter Sa-Prep (Coulter Corporation, the USA) and the evaluator of surface Beckman Coulter SA 3100.

Before carrying out of the analysis samples devolatilised at temperature 120
°s in vacuo within 1 hour. The presented method possesses an error of 10 %.
