“…Phase diagrams based on alkali metal halides, metaborates and carbonates are of practical interest from the point of view of boron carbide synthesis [1][2][3], which is used for the manufacture of grinding and abrasive materials [4][5][6][7], chemical glassware, protective plates of body armor, in electronics and nuclear industry [8][9][10], in thermonuclear installations [11,12]. On the other hand, it is of interest to synthesize oxide tungsten bronzes (OTB) of alkali metals in melts of metaborates, carbonates and alkali metal halides [13], widely used as electrochromic indicators, displays, optical modulators -"smart windows", exhibiting high corrosion resistance, thermal stability in a wide temperature range, metallic and semiconductor n-type electrical conductivity.…”

The phase diagram of a four-component reciprocal system Na, K‖Cl, BO2, CO3 into simplexes was triangulated, the main dominant chemical exchange reactions were revealed. It is shown that in a four-component reciprocal system, Na, K ‖ Cl, BO2, CO3, continuous rows of solid solutions based on sodium and potassium metaborates NaхК1-хBO2, sodium and potassium carbonates NaхК1-хСO3 are stable and do not disintegrate with the formation of eutectic. The phase diagram of the stable NaBO2-Na2СO3-КBO2-К2СO3-КCl pentatope of a four-component reciprocal system Na, К‖Cl, BO2, and CO3 was studied for the first time using the method of differential thermal analysis. It is shown that melts of a four-component reciprocal system Na, K ‖ Cl, BO2, CO3 can be used as media for the synthesis of oxide tungsten bronzes.

The magnetized coaxial plasma gun (MCPG) was investigated to seek possibilities of its application for a transient high heat testing to the ITER divertor surfaces. The experimental results showed that the MCPG could generate the hydrogen plasma stream with the ion energy of 50 eV, the peak energy density of 0.7 MJ/m2 and the discharge duration of ∼0.05 ms. This capability is enough powerful to melt tungsten materials. Vaporization of a thin surface layer and a cloud of dense vapor plasma in front of the carbon calorimeter were observed by spectroscopic measurements. © 2009 Institute of Electrical Engineers of Japan.
