| Реферат: | eng: Magnesium diboride obtained from magnesium and boron oxide by magnesium-thermal reduction in SHS mode under the high-pressure inert gas (argon) was investigated. The effect of pressure of inert gas on the temperature of synthesis and the yield of final product (magnesium diboride) was determined. As energy additives were used powerful oxidizers-potassium chlorate salt (KClO3) and ammonium nitrate (KNO3) to increase the reactivity of the system Mg-B2O3. The composite material containing up to 20% of magnesium diboride phase was obtained. The acidic separation of final product from impurities was suggested. The microstructure and characteristic of particle size was defined. The products had a dense grain structure with a particle size 200-500 nm. © 2017 Trans Tech Publications, Switzerland. |
