The paper proposes a mathematical model of the reactor, which describes the process of treatment of dispersed water-organic nitrate solutions of metals at air-plasma flow temperatures more than 1500 K. Regularities and a quantitative comparison were made to show the effect of the initial values of the air-plasma flow parameters (temperature, velocity) and the WONS droplet parameters (size, velocity) on the rate of their evaporation in the reactor. Process conditions were established that ensure a high evaporation rate of dispersed solutions in the airplasma flow. CALCULATION OF BURNING INDEXES AND COMPOSITIONS OF WONS Lower heat value and adiabatic combustion temperature of WONS including organic component (ethanol, acetone) and mixed water-nitric solutions of fissile materials (uranium, plutonium, and thorium) and matrix materials (beryllium and magnesium) are determined from formulas (1) and (2) [13]:

“…In this paper, the bulk ceramics sample based on molybdenum and copper powders was sintered using the spark plasma sintering technology. Unlike the existing methods [6,7], this technology makes it possible to obtain bulk samples based on powders in a short period of time that allows preserving the finegrained structure of the material and its unique properties. It is assumed that the molybdenum low thermal expansion and the copper excellent thermal conductivity will MATEC Web of Conferences provide substrates that can reliably dissipate heat in electrical components and help cool IGBT-modules, RF-modules, LED crystals and other products [8,9].…”

Abstract. In the article, the molybdenum and copper powders, obtained by electric explosion of wires and plasma-dynamic method, respectively, were sintered by spark plasma sintering technology, in order to obtain bulk sample based on them. X-ray diffractometry and scanning electron microscopy were carried out to study the chemical composition and structure of the resulting ceramics. XRD analysis showed that the product consisted of the following main phases such as molybdenum of a cubic crystalline structure (space group Im3m, No. 229) and copper of cubic system (space group Fm-3m, No. 225). The results of scanning electron microscopy indicated that the sintered sample had heterogeneous structure with the presence of small pores. Nonetheless, the mechanical properties such as hardness (Vickers hardness of 292 HV) and thermal conductivity (140.53 W / m · C) are good enough that allows considering the proposed synthesizing methods as well as sintering technology as promising for creating the Cu-Mo ceramics with high-mechanical properties.
