The purpose of the work is to create mass spectrometric, emission spectral techniques, analysis of new materials for which there are no standard samples, analysis of nanoforms of carbon in their mixture The thermo-kinetic characteristics of the decomposition reactions of carbon nano materials based on bulbs, graphite packets, cross-, cone-fibrous and coiled fibers, multi- and single-layer tubes at temperatures of 623K - 1273K were experimentally obtained. The proposed model of the size dependence of nano particles on concentration oxycene (2-) connected to peripheral carbon atoms (boron) with broken chemical bonds. A procedure for attestation of finished products of carbon nano materials has been developed. Using mathematical modeling and experimentally analyzed mass spectra of hydroxyapatite in a spark discharge. An atlas of molecular interferences was created during the analysis of this material. A mathematical model and a computer program were developed, the parameters of the spark discharge in air and the intensity of the spectral lines of atoms and ions of titanium and titanium boride were calculated. The concept of analysis of new refractory materials based on titanium boride using standard samples of titanium alloys was developed. Alloys of the Cu–In–Yb ternary system are of interest from the point of view of technological application, mainly as new magnetic materials. The method of isoperibolic calorimetry determined the partial and integral enthalpies of mixing of melts in the range of compositions 0 < xYb < 0.7 of the Cu–Yb system and 5 radial cross sections of the Cu–In–Yb system up to x3< 0.3 at temperatures of 1453–1473K.
